Building a HUGE Pond Filter - Part 4 - Moving Bed / Fluidized Media Chamber

[@pondguru]

Forth episode in this mega-filter build for my large trout pond. Today we will take a look at the moving bed chamber and concentrate on the perforated outlet, drain and outlets to the next chamber. Toward the end of this video I go into depth about the pros and cons of different types of moving bed / fluidized bed filter media media and explain how you can boost the biological activity in your moving bed by 40% simply by making the right media choice. Why spend thousands on a fancy filter system and have it under-performing? A cheap DIY moving bed filter with the right media will easily outperform a ready made one with the wrong media.... *Please check with the manufacturer of your moving bed if it will take K1 micro without modification - most will not, therefore the Hel-x 13 would be the better choice instead of K1 standard size* (Both the Hel-x and K1 micro offer approx. 40% more surface area per litre compared to standard K1) The next episode will highlight the two static bed chambers which will be filled with a nation of media. *When using side pressure to cut a hole with a drill bit use safety glasses since a broken drill bit is a sharp object which can damage eyes.

Pondguru brilliant update! When’s part 5 coming the waits killing me

[@slingyourhook7526]

Hi great video as always. Where can i buy the white mesh pipe from. Cheers.

[@pondguru]

Hopefully the some time next week as I have shot the footage, just needs editing. The filter is just about finished now but I still need a big pump to feed it.

[@pondguru]

Sorry I forgot to put a link in the video description for that. It is called 110 perforated pipe (1000mm length) but can I hell find any suppliers online. I think you may have to contact Kockney Koi directly for that - I just added it onto an order for foams a month or two back. Their number is 08448000000

[@kev231184]

It’s a quality set up, how much volume will the filter on its own take! Keep up the good work chap I love this channel

[@MARKSAQUATICS]

Looking good mate! I can see you pond crystal clear with the trout slowly moving through the water taking those newly hatched flies off the surface while you sit on the deck watching with a nice cold beer. Great job so far.

[@pondguru]

A clear pond would be a major boost to the way it looks and it's been clear before so it could be clear again. However I recently had a 5 foot sturgeon dropped off by a local koi place which closed down and this was the most suitable pond for it.....that may have been a mistake to put a very large, active bottom feeder in as far as water clarity goes for a clay lined pond, lol

[@seekingthetruth9896]

The suspense/anxiety is killing me. I want to see it in action, also the resulting water quality.

[@AquariumCop]

Brilliant info, well explained! Thank you brother ✌💞WE know you originated this that's why we love you! ✊👊One day I'll retire and if I'm lucky enough to make a pond - I'll be referring to your channel for sure . I'm still watching .

[@pondguru]

lol, I'm glad you find the videos useful - thanks for watching.

[@Matt_corns]

Fantastic as usual.. looking forward to the next video

[@emersonbrown1019]

Where did you get the mesh piping you used in the filter. That might help solve my filter flow issues.

[@davidparry2301]

Don't have a pond, I'm an aquarium man but loving the videos. Can't wait for the big switch on. More exciting than Christmas lights ;-)

[@magzire]

Shouldn't the venturi tube slit be face down not up? I always thought the angle should be away from the current, not against

[@TheWildWondersSA]

Great video Richard. Really looking forward to seeing how your moving bed section will work. (Almost at 100 000 subs)

[@j.michaelwilhelm7349]

Nice job again Richard. It'll be hard looking at ya with one arm and one leg missing..as this filtering beast is going to cost that for sure. Looking forward to seeing your static bed filter design. Interesting.. that I came across one of your coharts on You Tube that touts he has degrees in biology or something and yet his narrative constantly reverses Nitrites are Nitrates and vise versa. We were discussing the static bed and Bio-Home type media...his take on those is that they don't work at all and doesn't using them. Basically saying that studies prove that the bio-mass is so thick on the outside of the media (I think he is referring to aerobic bacteria, which should be correct) that these studies prove that the aerobic bacteria cannot colonize because there is no water flow??? This seems odd, as that environment I would think would be perfect....very low flow of water. Even some very expensive filters that come pre loaded with anaerobic bacteria and a small submersible water pump is designed to flow mere drops of water back into the aquarium. I wonder where can I read these reports for myself. Anyway looking forward to see your static bed design.

[@justgotravel6646]

Is it possiple to cut up a matress in small pieces and use that instead as a cheaper solution maybe add some plastic caps from soda bottles.

[@jasonsheridan2548]

Where can you purchase them big tanks?

[@andrewdavies5103]

Where do you buy the white perforated pipe from please

[@readmore7180]

Can someone enlighten me to the point of the white perforated pipe at top of filter ?

[@davidbrown9493]

Love all the videos fella keep them coming thank you for taking the time to keep us updated

[@danusb2]

Thank you for the great video keep up the great work

[@demacherius1]

Im gonna steal alot of your ideas for my Aquarium. Pleas do me a favor and level the Volume because it nearly gives me a hart attack every time you turn on a tool.

[@pondguru]

My video editing software isn't advanced enough to have any volume leveling tool on it unfortunately. However having the occasional loud noise may help to keep people awake during the video as I've been told on many occasions my voice is incredibly boring, lol

[@sharkbit61]

Hey! Leave Joey alone!

I am not sure this series even finished at all.

[@dawndixon1585]

Comein on great Richard, can't wait to see your next video as i love watching people make or build things & to see the end result as a lot of thought has gone into that enormous filter, & yes i had my ipad turned up so i could here what u were sayin & when it went on to you cutting the pipe the noise off the cutter i nearly fell off me chair 😂

[@pondguru]

That burst of loud noise just helps to stop people falling sleep from my boring voice, lol

[@steveoutdoors5964]

If you have an aldi store nearby they recently had a selection of tools on offer. One that would be of use to you is the set of drill saw bits. Drill bits specifically designed for cutting holes as you do with a standard bit. They also had some universes of circular saw blades in a variety of sizes. Filters coming on great. ATB Steve

[@pondguru]

Good one, all the pipes are fitted in place now but I may invest in one as I will probably be adding something extra over the static bed parts of the filter. Hope you're well, man

[@johnrusson7810]

Excelent thank you

[@Cichlids23]

hahaha....Dont worry Richard, I found your channel before Joeys and I know you got mad skillz!!

[@pondguru]

I had to edit out loads from that bit where I was mentioning people stealing ideas as I was picturing that guy going on a rant about people stealing his ideas and copying him and all I could think was "That's the pot calling the kettle black" and I couldn't stop laughing - I looked like some mental patient, lol At the end of the day there probably aren't any original ideas and I'm sure that some of the ideas I have put out there have been done by other people previously somewhere in the world but I wouldn't knowingly steal someone's idea and pass it off as my own for 5 minutes of fake fame as that would be a very hollow feeling, not to mention dishonest too. There's certainly nothing wrong with people using others ideas if they can relay the information in a different or better presented manner and god knows most people present things better than me so I'm all for sharing ideas around when sources are referenced - I have even thought of re-doing some of my very old videos as the presentation is awful and my voice was even more boring on those videos than it is now (if that is possible....)

[@SiHill80]

Not convinced those venturi pipes are going to work. The theory is obviously correct but I think the direction of the cutout is actually going to collect the water flow and force it up and possibly out of the green pipes. The cutouts need rotating 180 degrees to point downwards so the water moving past sucks the air in as it goes past.

[@pondguru]

Somebody else previously mentioned that too and I reckon you both have a point. It is working OK with the limited 12000 pump I'm using to test the filter (for level and leaks etc.) but with a bigger flow from a big pump that alteration of the pipes can (and probably will) make all the difference - thanks for the comment.

[@SiHill80]

Ah sorry, I did quickly skim the comments before I posted and didn't see it mentioned. I see it now as a reply to a different comment.

[@pondguru]

No worries, I don't mind being called out on my nonsense multiple times, lol

[@modelchrissteam]

Well spotted Simon ( didn't notice that first time of looking.) Richard generally knows what he's talking about though.haha (No offence Richard).

[@pondguru]

My head is so done in with the amount of work I have on at present that I'm sure I made many more mistakes than the pipes. I love it when I get called out on something as it enables me to learn from shared information (from people who know better than me, lol) and I could think of nothing worse than an Emperors New Clothes situation where everyone was reluctant to call me out on something.

[@graemejohnson2388]

Hi Richard I seen the sturgeon the the koi place that closed. It was a beast of a fish. Real shame about the place as I been going up there as far as I can remember. Only got place on valley now and I think it’s expensive.

[@pondguru]

Yes the independent places are disappearing and we will be soon in a situation like the US where everywhere is a Petsmart. I rarely see that beast of a fish but when I throw food in I can see bubbles rising up from the bottom of the pond so it is keeping it stirred up which should be really good for the health of the pond since there is bound to be a nation of old leaves in there - hopefully the filter will catch the muck getting stirred up and the sturgeon will eat the crayfish which are digging into the clay base. I can only imagine how big it will grow in here, lol

[@TheOllymo]

Hi, could you advise on where to source the mesh tube from? Thanks

[@pondguru]

That was from Kockney Koi and it is a 1m x 100mm mesh tube. It's a handy thing for DIY filters.

[@JayJay-lu2lo]

Hi , this question is somewhat unrelated to your video and for that I apologise, products on the market for speeding up the cycling of the filter (good bacteria) is there any difference between the pond bombs or the aquarium bombs or can either product be used in either situation , many thanks jay

[@pondguru]

There is no difference in the bacteria they contain but the 'aquarium' versions of gel balls tend to be clear and way more expensive....use the pond balls.

[@gregjonesonline]

friendly tip: when you push the pvc pipe in, keep applying pressure for 10-15 seconds to avoid it popping back out, you can see it move in the video

[@pondguru]

Thanks for that tip - none of those joints are leaking but if they were that would probably be why, lol

[@barrydesmond9288]

Thanks for explaining the cycle of media now to get out and try change my old green multi filter chamber filter ...thanks 👍👍👍👍

[@jamespuig4858]

Keep rambling its fascinating and I' learning

[@pondguru]

No worries, I'll talk nonsense and ramble until the day I die, lol

[@AlanMolstad]

I have my doubts... I mean I sure hope it works and I sure hope that this filter design will turn out to be good enough to handle the whole pond, but...I have my doubts. Im a subscribed fan and I have learned a lot, and really all I know about cleaning water, be it in an aquarium or a fish pond are the things I have learned here from your videos, but....based on your other videos I cant find a way that this current design will be large enough to handle the job you are asking of it. When I look at the size of your pond, and what I think it would take to clear its water I cant help but think that my only hope of success would be to use like, 8 to 10 of the luge 270 gal tubs I see others use for jobs like this, www.plastic-mart.com/db_images/pm/rebottled_ibc_totes_caged_water_tanks_cat200.jpg But dont ask me how to set that up cuz I would not have any idea...

lol, yeah, but there is way more than one dong in this hobby and while I appreciate that there are now very few original ideas it takes a special sort of person never to reference where the 'inspiration' came from but that's just what people are like now - taking credit for the work of someone else is awful and must be hollow feeling but it goes on all the time. I used to get riled up about it but now I just think it's kinda funny as anyone with a penchant for crapping on people get found out pretty quickly by the genuine folks and shunned. I'd rather be Mr. Obscure and well thought of than raking in money dishonestly as I've said so many times the pursuit of money is the pursuit of suffering.

[@Fishing_Addiction_Miami]

Very cool!!! Great work!! Nice video!!!

[@AquariumAdventures]

Looks good! Strange question - but do you think it will be noisy? I've considered a moving bed in my aquarium sump but initial trails were annoyingly noisy

[@rantsandreviews]

I have an 8 gallon MBF running about 10 feet from my bed. It is a little noisy...kind of a constant ssshhhhh sound. I put a lid on it and it was fine.

[@pondguru]

I have the feed pipes just about at water level and it is quite quiet but I may notice more noise when I get a large pump running the system. I may even have to drive the bed with an air pump but I'll see how it goes. I've got a sauna in the cabin above the filter and the sound of water creates a natural 'white noise' for enhanced meditation, lol I did 45mins at close to 100 degrees C the other night but only managed 30 minutes on the top shelf and 15 minutes on bottom shelf.

[@markmmm1737]

I don't think the moving bed will be the loudest thing. 10 pipes of venturi is going to be pretty loud, however the sound can be baffled or use very long pipes. Just have to see when it's running at maximum capacity.

[@tonypizzaman985]

[@IFIXCASTLES]

Fill one of those black containers with biohome ultimate .....too expensive you say? Lol

[@pondguru]

I got 750kg of alfagrog in 2 of the containers and that will do for them as the water isn't going to be perfectly clean for a really good, porous media. I will fill the showers with a mixture of biohome and pumice as the water there will be much cleaner.

[@kyle5709]

I"m ready for the next video!!!

[@GRPLiningServices]

Richard what's the nitrate level in the pond at present please?

[@pondguru]

I really should test it some time then compare it 6 months later when the filter has been running but I'm not really expecting the filter to affect nitrate (no way enough media), just restoring clarity will be a major win for this one.

[@MT-jf1tn]

I can’t wait to see up and running!

[@james-5560]

It would be good if there was any way to measure the before and after water clarity with a meter or even just sharing video with us at the various stages. I'm absolutely loving this series and please show lots of videos of it working!

[@pondguru]

The water is going through it now using a smaller pump (12000 lph) to test for leaks, static beds are full of 750kg alfagrog but I will be putting another 200-250kg in the shower container followed by about 300kg of shower media. The water seems to be clearing a bit already in the pond but it is too early to say for sure.

[@StanTheObserver-lo8rx]

Another idea? Use a backhoe to carve into the bank and farther into the yard..put in tons of lava or like that into a lined over cinder block area or even built up with treated wood, and plant water plants while water is pumped over all that and runs down to a big drain pip with a jillion holes and then back into the pond. For that huge pond,a gravel bed of 20 x 20' x 4' deep sounds like a start.

[@pondguru]

I was going to install a huge stream coming down the bank near the pond coming out of a tunnel and using alfagrog behind the walls flanking the sides of it but the quarry I used to get stone from closed down and killed that idea so I went with more traditional filter to enable me to use waste water to feed parts of my garden and (hopefully) restore clarity to the pond.

[@EpicDesignSolutions]

funny Joe said the same thing about the k1 media and him starting the trend. i believe u though

[@pondguru]

lol, that sounds about right. Here's the first video and I did variations in other videos shortly after that: kzbin.info/www/bejne/rGPIe4abfZJoldU I'm glad the idea caught on as a moving bed can really help hammer the ammonia and nitrates and it will be the idea which is remembered, not whoever claims to have come up with the idea.

[@banksarenotyourfriends]

I've got plans to make a 1000-2000L aquaponics system in 2019 (I'm just West of Hexham) - I'm thinking I'm going to have lots of questions that you'll be able to answer... I'd be interested to know what you think about keeping small numbers of fish in IBC containers - from the fish's point of view I mean? I intend to build both moving and static bed filters, along with a small vortex filter, but only use the static beds throughout the winter when the plant growth is low. If I can find a supplier that would sell me small enough quantities of fingerlings, and build a setup with high flow rates and clean enough water, I'd eventually like to expand the idea and try growing trout rather than goldfish - which is what I planned to start with on my initial build (obviously, am not eating the fish that time round - just the veggies lol). What do you think? Am I cream crackers or is this a feasible way of growing some fish?! Smashing videos by the way, I envy your pond setup!

[@pondguru]

I'm personally not a fan of growing food this way as it is very intensive and fish need space to develop proper muscle meat. Slow moving fish like Tilapia seem OK for growing in aquaponics systems but they won't survive our climate - best to have a very large pond to grow our UK species of fish but the actual set up you propose sounds sensible. Feel free to phone any time or swing by to see what the filter I'm building is composed of, no worries. 07772848730 Regards, Richard

[@banksarenotyourfriends]

@@pondguru Thanks for the swift reply! That was my concern, that there wouldn't be enough room for the fish. My intention is to maybe have 8-10 500g fish per 1000L tank by the time they are taken out for food, so maybe that's enough space for a slower species. You're dead right about the temperatures, and that's what led me to the Trout - Catfish were another thought, but in the words of my friend, I would "struggle to have it not taste like s**t"! (he's a chef with an aquatics habit/hobby). I think I'll try the system with the goldfish, and see how I get on, and have plenty time to think in the meantime. I'll not have the thing built and cycled before the spring now anyway, but your videos are very helpful - particularly this mahoosive pond filter series! I'd love to see it in action once you've got it all running exactly how you want it, so I might give you a shout on the phone once you've got that far. Thanks again for the advice. All the best, Andrew.

[@banksarenotyourfriends]

@@pondguru by the way, I'm itching to see the next video in this series, any idea when it'll be up?

[@pondguru]

@@banksarenotyourfriends Getting good tasting fish will be a major battle, even when filtration is perfect on a small system as the diet will be restricted compared to a natural pond / river environment but if you could integrate a water cress bed into the system the roots would support a vast amount of water lice and shrimps to feed the fish naturally and supplement a pellet diet. Yes no worries feel free to ring any time as the filter is running now, just need to finish the shower filter part and get a bigger pump for it (ideally something between 20k - 30k per hour) then I can use the 12k pump for the showers. I had thought of integrating the large aquarium I have there into the filter system but that may have something a bit different going on in it with regard to filtration.

[@banksarenotyourfriends]

@@pondguru Thank you for that - the water cress idea makes a lot of sense, I'll have to look into that. I was intending on using a couple of deep beds with clay balls for growing the plants in, but perhaps I could also have the water cress on a floating raft in the tank with the fish, or give it an adjacent, smaller water tank connected to the fish tank. I'm gonna have to have a long hard think, as you've given me plenty food for thought there. Really appreciate it, cheers. I'll see when I can get a day off to come and take a look at your project - I think you're slightly mad, but in exactly the right way (!), and this whole series is really inspiring. Thanks for documenting it.

[@elmee96]

I love this channel! If it weren't for you i still would have thought that waterchange once a week keeps the nitrates down to a good level. Really thankfull for the info you bring. Keeps my aquariums as healthy as they can be.

[@pondguru]

Sounds good to me and I'm glad the videos have been useful as that's why I make them - free sharing of ideas.

[@markmmm1737]

You should know that you don't need to worry about the water quality of your filter. Your pond is already doing a fine job of looking after it self in a green kind of way. Your filter can only improve what nature is already doing.

[@pondguru]

Yes the flora and fauna in and around the pond tells the full story of water health but it's really the clarity that I want to be better and well over half of this system should contribute toward that goal. Having any pollutants worked on is a bonus too - just added 750kg of alfagrog in the 2 next chambers, lol

[@predatory_fish_keeper_9553]

Great video, I learned a lot from watching your stuff. The Joey reference was kind of funny though

[@pondguru]

lol, yeah people naturally assume that I have some major beef with him just because he took one of my ideas and many of other people's ideas and presented them as his own but (while it's not exactly an honest thing to do) it has ensured that the ideas get out there and that helps to benefit the community so it's all good with me. Really it's no different from a channel with 10 subs stealing someone else's ideas and it tends to be what some characters do so people need to get over it. When you put ideas out there the genuine characters will reference where they saw the idea but not everyone is like that and I'm sure if I was treating the channel as a business I'd be desperately looking for new content to allow for as many uploads as it takes for a channel to go viral so it's entirely natural to run out of ideas. I'm glad you enjoy the videos - thanks for watching.

[@scottgibson7534]

Hi Richard, you might want to go round your 4" Bulkhead fittings and change out the coated steel screws and replace them with the same diameter/length stainless steel screws= no rust in the future.

[@pondguru]

The screws are coated but as I mentioned in previous video (you're right) stainless would be the way to go.

[@eisenklad]

i do hope you have a kit measurinng the water parameters before this mega filter is powered on. and everytime you do a pond update, you can do a quick test to show how well the filter has matured. once the results have plateaued then you can stop taking the test. kinda like what Aquarium Adventures did on his BioHome long term test video

[@pondguru]

I don't think the filter will be big enough to affect the quality of water as that is already good but the clarity is that main concern. If I can restore clarity that will be a major win and I'm hoping the static parts of the filter will be a breeding ground for invertebrates which will serve as fish food when they make their way through the system and out to the pond.

[@MrChillen22]

Great video really looking forward to seeing it done read through some of the comments on the Venturi pipes I’ve seen other people restricting the flow of water just before the point where the air pipe is connected is this necessary or will plenty of air be dragged into the system doing something similar to what you’ve done ? I’m looking at adding a moving bed filter to my system for next season

[@pondguru]

There may be enough air dragged in just from the outlet of the brush chamber and as it falls so far it should mix well with water in the moving bed part but time will tell - I don't have a big pump for the system yet.

It is just about finished now - just need to fill up the shower filters, install a double socket and get a big pump to feed the system. Currently it is running with the 12000 lph pump to test. Editing is what kills me as I get so little free time but I hope to have the next up next week some time.

[@TheCourageousLink]

cant wait to see it in action

[@rustytwinkles7762]

great video pondguru and i really enjoy watching your videos and because i do i bought your FRESHWATER 5KG EXTERNAL FILTER UPGRADE KIT from your website for mine my filter and i tested my nitrate and nitright levels today about a week and a half and it was 0 on both and my ph was perfect so just wanted to say thank you... p.s thank you for the extra white pad

[@pondguru]

Awesome result but that is suspiciously quick for a full cycle - are you using any additives with liquid carbon? that would speed up the development of bacteria significantly.

[@rustytwinkles7762]

hi ponguru no i just put the 5kg of Biohome Ultimate in and the pads and the filter starter jelly balls in and i have put in the water the tap safe and thats it nothing else has gone in no liquid carbon no carbon in the filter.. i filled up the tank on the 11th of October and the filter has been on since then and i tested it on the 17th of October.. my filter is a AQUARIUM FISH TANK EXTERNAL FILTER EFX+ 2000L/H 9W UV STERILISER from all pond solutions. and my tank is a fluval roma 240.. thank you for replying back

[@pondguru]

It could be that the nitrite and nitrate haven't had a chance to rise yet maybe? Generally it takes 2-3 weeks for the aerobic part of the cycle (0 ammonia, 0 nitrite) then anywhere from 1-6 months for the anaerobic part of the cycle (nitrate reduction). We have had a few reports over the years where ammonia, nitrite and nitrate remain zero after the first week and beyond, even when a tank gets fully stocked and I'm still bemused at those cases.

[@tednguyen4771]

Fantastic project Richard! When will the next one?

[@pondguru]

Filter is almost finished now and I have shot next 2 parts but getting any time for editing is very hard at present.

[@FudgeMonkeySmurf]

What are your current water parameters in your pond prior to filtration?

[@pondguru]

I should really test it but the main aim of the filter is to clear the water. It's thriving with all sort of life from big fish down to a nation of invertebrates but more clarity would be nice. When it gets up and running I'll test the water from the far end of the pond where all the uneaten food collects and also at the filter outlet as that will probably be the best indicator of any change but the filter probably won't mature until well into next spring. Hopefully by then it will be clear too...

[@charlie10tango39]

can you post a link to where that perforated pipe can be purchased?

[@pondguru]

I can't find it online but I got mine directly from Kockney Koi so they would be the best to contact for suppliers - perfect for this application.

[@chrismcerlain1664]

Looking good. Could you tell me where to get the perforated pipe please ? I have got loads of uses for that in my filter.

[@pondguru]

It was from Kockney Koi in the UK - if you contact them they should be able to tell you who stocks it. Next part uploading now.

[@propsygun6024]

it could be that more than 1 person came up with the ideer, it happens all the time. looking foreward 2 the next video, been thinking about that kind of filter 4 a long time, and i cant see how u r gonna do it with that setup, i would have put it before the moving bed. but idk the complete setup yet... that kind of waterflow, and open tubs, nope im lost. :)

[@pondguru]

The first video in the series explains the full set up but when I get the various parts of the build all uploaded I will then collate them all into one very edited down video which will hopefully be easier to watch and make more sense as it will be a straight progression from beginning to end. On the subject of people passing off others ideas as their own there are way too many people at it. I even had one guy (quite well known, 10's of thousands of subs) replicate the 'how to set up a canister filter' video I did a few years back and miss out the most important information from it regarding anaerobic bacteria, presumably as he couldn't comprehend what it was useful for. Could be a coincidence? Well, he copy and pasted the full description from my video minus the important links to further information and put that as his description. Proper amateur thief...... At least the fakers higher up the food chain on KZbin have the fully developed skills to block you first before they pass off something as their own idea and take the time to add their own video descriptions to make the deception more believable for sheeple, lol

[@propsygun6024]

hahaha, really! thats funny, its so sad that people steal ideers. A lot of mine, i found 2 be invented before, or something close 2 it, some bether some worse. Just seen the first video, still cant see it. :D So u want the Alfagrog's internal anaerobic bacteria 2 do the removing. with the outside aerobic, since u have all that flow, mby u dont force it through the media, but just over it, like a deep gravel in akvariums? it would be really stable, but not really effektive, and a pain 2 clean. Why do u do this 2 me? its like a riddle, kind of like it. A link 2 a normal sulfur reaktor. reefkeeping.com/issues/2009-01/diy/index.php It would be great 2 get the solids out of the water, and use less watts on lifting the water, but i like the budget diy theme. I didnt know the shower came after, sry. The microlife is a very cool ideer.

[@pondguru]

Yes the crates of alfagrog will be basically replicating an idea I saw 20+ years ago which used pumice cat litter in trays of a slow moving tank for nitrate removal in a koi pond - the idea is still reasonably popular in Europe and has been mentioned a few times in KZbin videos - often called anoxic or biocensus? (or something similar) filtration. The last video on a system like that for an aquarium has some joker in the US claiming that he invented it so I turned it off, lol The majority of the water in the static beds will go around the outside of the media crates.

[@propsygun6024]

hm, clever, so u can move the crates 4 cleaning, and only a bit of water goes in the middle of the crates, thats smart, r u gonna use sulfur, in the middle of the crates? it rly boost the life. its save if u do it right. Im from Denmark, didnt know kalness came from here, well the US really like inventors, and pride. it makes 4 a wierd combo, where people lie a lot, so they can be proud of being the first one. They r so religious but have forgotten the death-sin Pride! hehe I have an ideer 4 a screen filter, like drum, or sieve, but i dont have a pond since i moved, even sold my aqariums. :( looking at youtube is not the same. I can send u the plan if u wanna do something different as mekanikal pre filter at some point, i cant claim im the inventor, just because i havent seen anyone els do it. ;) now stop talking 2 your viewers an make more videos, we cant wait. ;)

[@hollyfifa775]

Why aren’t you filling it with biohome ultimate 😉

[@pondguru]

The showers will have good media in including biohome of various types and white pumice as water will be much cleaner in that section.

The filter is just about finished and I have more moving bed media on the way, all the alfagrog is in static beds and I just need a big pump and the shower filter part putting together - I'm just way behind on the editing, lol

Ok, great to hear that, just take your time, take care of yourself, don't over rush.

[@jameshebrard9354]

Great job, as usual, Sir. How much planning did you do before you started building the filter? Did you make diagrams, calculate water volumes and flows, etc. Or , are you planning as you go? Much respect!

[@pondguru]

Planning? what is this thing you call 'Planning'? lol, I just make it up as I go along and have been collecting the various parts for about 10 years. When I have a plan I throw it into the ether and things just work out over time.

[@sparkymark68]

Just wondering. If you extend 1 or 2 of your venturi tubes to the bottom of the chamber, would this add more air agitation? Love these videos!

[@pondguru]

It would probably enable air to be dragged right down to the bottom but the moving bed media tends to operate in the top 2/3 of a container, even when it is fully mature. I've got a 6000 lph pump in there shifting it around now but I reckon I'm going to go with an air pump with a DIY air pipe attached to the drain pipes as they are perfectly placed to distribute air and move the media properly. Having that in addition to the water falling into it with a big pump should really shift the media well.

[@sparkymark68]

@@pondguru just a thought. Looking forward to the next installment. Thanks Richard

[@richiejp2965]

Fantastic video as ever. Quick question where did you get the large tanks?

[@pondguru]

I got them from various sources and the round one is best as quarantine tank since the rectangle ones deform when they are filled with water. If you look up 'Champion moldings' (nr. Manchester) they will manufacture them in loads of sizes.

[@richiejp2965]

@@pondguru Thank you I will have a look at them. I'm after one for a quarantine tank

[@fossphur]

Lol ouch! headphones warning for that chopsaw, what a squeal! Looking great so far :D

[@fossphur]

Actually just got to the bit with the DIY venturi, I feel like that's backwards and might get you two jets of water instead of two sucking air pipes. I thought the idea was to have the water rush past either side of the insert with the notch/angle facing away from the flow, there will be a low pressure zone created in the hose in front of the inserted part, and that will make it suck air. I don't know though so I'm keen to see what happens! You're the Pondguru after all not me lol

[@pondguru]

If it doesn't work too good like it is in the proper flow (when I get the big pump) I will turn the ends of pipe around and if it still doesn't work I'll scrap the idea, lol Actually what you're saying makes sense there.......thanks for that. I only have a 12000 lph pump operating at present so there is barely a trickle compared to when I get a proper sized pump. The last thing I want is water squirting out of the 'air' pipes.

[@nicholsceramiccoating8284]

Love it! Thanks for all of the info in your videos, its really making me rethink my filtration system for the next year

[@pondguru]

No worries, I'm chipping away at this project when I can but it still is not finished. It's running with a small pump (12k per hour) but I still need to finish the shower part and alter the moving bed to include an air ring around the bottom drain for extra media movement but apart from that (and a big pump purchase) it is done. The large aquarium I have there will be getting used as a part of the filter too but that is a really unusual 'filter' idea which I haven't seen used anywhere so it's under wraps until I get the necessary (living) parts for that one.

[@nicholsceramiccoating8284]

Awesome, hopefully we get to see another video on that soon.

[@ultimatefishkeeping]

The way this information was delivered was excellent if I say so myself. I am sure many will benefit from this, and I was agreeing with everything you said. Thank you for sharing, gave a like.

[@pondguru]

I'm glad you enjoyed the video. When the filter is complete I will edit all the parts down into something much more watchable with any waffle or repeat information cut out but that probably won't get edited down for a good while.

[@ultimatefishkeeping]

No worries. You are doing a great job of that. Have a great weekend Sir.

[@pondguru]

You too, although half the weekend has gone already. We either need a 8 day week or a 4 day working week and 3 day weekend. Working mad hours 7 days a week is no good.....lol

[@ultimatefishkeeping]

Thank you very much. Laugh out Loud, you can say that again. I have been working 7 days straight. My wife is not happy because of that.

[@pondguru]

I think mine has just got used to it as she is also works mad hours - there should be a capped 4 day working week by law I reckon.

[@StanTheObserver-lo8rx]

The thing about all that plastic media?..its all got a smooth surface. Shiny. I would think there must be some kind of acid dip for them to rough them up? Or tumble in sharp sands and all that would double or more the surface area. Or,if you have the time leave all that new shiny plastic in the hot UV summer sun to take the shine off. Seems to me that would make them equal to porous stone without the weight.

[@StanTheObserver-lo8rx]

Whats that?

[@pondguru]

lol at the clay - I added about 20kg over the moving bed media on the first day of running it to encourage it to move and to add trace elements into the system.

[@pondguru]

It is running but only with a 12000 lph pump and I haven't got the shower part ready yet as I need a few more crates for media in the tub there and it will require the 12000 lph pump for that part. I'm also going to add something which I don't think has been seen in a pond filter before too but I will need to get something really specific for that part - it will utilize the large aquarium I have there as part of the filter but nobody would be able to guess what will be going on in there.

I currently have a water butt as a radial flow filter so all big bits sinks to the bottom and then it exits over filter floss changed every 2 days before dropping into the static bed. After the moving bed it goes into a mini bakki shower with a piece of jap mat at the top and then pumice stone in the bakki. Then down a waterfall. I have always struggled with nitrates of around 40/60 so anything i can do to reduce that would be great.
