Can you recommend some dechlorinators please. I can't find just plain dechlorinators, they all say they stop metals too :(

[@ThousandYardStare]

@@quantumsneak1773 I always recommend API stress coat as I've never heard of anyone having problems maturing a filter while using that one and it is very popular. Basically as long as you avoid any dechlorinators claiming to remove / bind ammonia, nitrate or nitrate you're good.

[@Sunny-wp4fd]

How long per day should have to run the sump pump. There is sponge filter running all day.

[@pondguru]

Ideally every pump which is moving water through a filter would operate 24/7 since the bacteria living inside the filter (foams and media) wants to be exposed to as much 'food' as possible. When a filter runs 24/7 it creates much more stable water conditions.

[@runcmd8851]

Great Video Pondguru... But I would advise people not to put the Heater in the same section as the pump.. As if there is a drain issue or power outage the pump could leave the heater dry causing heater failure.. Great advise on what media to use..

[@noodlesandwich8773]

[@stucody]

Maxspect blocks do get good reviews

[@wiggledytoes]

Haha glad your keeping an eye on foreign affairs. I use alfagrog, could that be causing my goldfish opaque eye?

[@pondguru]

The filter media won't affect the fish that way unless it is in a biorb or similar tank where fish can damage themselves directly on sharp media like alfagrog but a treatment like Melafix is great for cloudy eyes.

[@ProTexTV]

NEVER put the heater in the return chamber. Without an ATO or with an ATO malfunction. That's the first chamber to go low.

[@neddelic]

jbl Oxygen test kit O2 purchase one. magic sponge cleaning industrial supplies purchase the long ones

[@CrazyAquariumGuy]

Great video as usual. The older you get the more you regret not setting up more sumpfiltryers instead of cannisters. 😃

[@pondguru]

For sure - the first few times you maintain a canister it is novel and relatively quick then it soon becomes a hassle, lol

[@YT-Hades]

Everyone forgets to tell us noobs how you pump the water into the sump tank is doest is cyphen

[@BenOchart]

Good timing Richard, I’m right in the middle of setting up a DIY sump for my 210 gal. One point I picked up from the reefing community (BRS)- Never put the heater in the final pump compartment. If the overflow gets blocked or if there is a lot of evaporation (common with sumps without an ATO), the pump chamber will run dry and that heater will malfunction and possibly catch fire and/or melt an acrylic sump. Hope things are getting back to normal in the UK. Be well.

[@stevendiaz2257]

So where do you recommend to place the heater? I’m thinking of building one

[@BenOchart]

@@stevendiaz2257 Middle compartment that will remain full (to the top of the glass wall) when the tank overflow becomes blocked or evaporation has lowered the waterline below the weir (cut-outs in the overflow). The pump will empty out it's compartment and if the heater is in there you will get a melt down.

[@pondguru]

That is a very good point which I overlooked and as the final transit to the pump chamber is over the top that is where the water loss will be expressed so the heater should indeed be one chamber back. With regard to getting back to normal in the UK we have no chance of that as the people behind this nonsense are going all-in to destroy our country. It is like what Cuomo and Newsom have done to parts of the US x10. We certainly live in interesting times, lol

[@localguide583]

Thank you for taking the time to go over each step and product for building a great sump. This is the best video that I have seen to help me with my first ever sump.

[@Sahadi420]

11:24 about made me choke on my water...wasn't expecting that at all!!

[@pondguru]

I was gong to work the 'hairy legs' quote in too but I'll save that for another video.

[@zlamanit]

Great video but there I see one problem - it's best to not install a heater next to the return pump, because it's the only part of the sump that may get dry. Which would mean running the heater dry.

[@ThousandYardStare]

(my other channel) That's a great point and without an automatic top-up (which all sumps should have) the heater is better placed in the second to last chamber as you've suggested. Sorry, I forgot to mention an auto-top up since I never plan what I'm going to say in any of my videos.

[@shiva5718]

Amazing video mate thank you! Have always had canisters and now upgrading to a 10x2.5x2.5 with my first sump. Appreciated!

[@mgl63823]

Another great video from the GURU. Great to watch all on point.

[@KennethFarley-mq9mo]

The best sump filter is a fluidized k-1 sump

[@thegamesource]

Please do not ever put your heater in the same area as your output pump. You are asking for trouble if that area ever dried up for whatever reason. Always keep your heater in the middle section where there is always going to be water no matter what happens.

[@pondguru]

That is a good point which a few other people have pointed out - I always used to have auto-top up systems on ponds, sumps etc. so I neglected to mention that.

[@craigrafferty4159]

What happened to the Mega filter for your pond?

[@pondguru]

You can see it in the garden video I did recently - the first chapter is about the filter.

[@nightlite9009]

Why're sumps made of glass though? Wouldn't they be cheaper in Acrylic?

[@pondguru]

If acrylic was more widely used the price would surely come down but glass is readily available and easy to work with so the price is way lower. Making sumps from acrylic would definitely make sense since a glass sump is so heavy compared to acrylic. Acrylic is so easy to drill and alter too compared to glass.

[@simonsepic]

I made something you might like. I started building my own invisible filters with a twist. I got a large sponge filter reccomended for upto 300l then I got loads of lava rock and carefully glued it all the way around the sponge. So my theory is after enough time has passed and the sponge is all clogged the slow flow of the sponge drawing through the lava rock enables the nitrate cycle. I have a canister on the same tank. While I should get round to testing the water I still havnt because I set this up on a tank I setup at my mums house. Anyway 8 months in and her tank has gone from 4 kribensis and 2 turtles to about 100 kribs and 2 large turtles. No issues whatsoever on a tank that is a little neglected because I'm the only one to do anything to it.

[@pondguru]

Sounds good to me, man.

[@terpax]

Wouldn't the protein skimmer be better before all the bio-media? Not sure how much excess nutrient will remain after filtering through all that.

[@ThousandYardStare]

(my other channel) That would work no problem - it can either go before or after the biological media - I just has it before since I was working with a small sump and it was not as easy to get clear water around the skimmer in that scenario.

[@galejohnson8086]

Don’t you mean anoxic, not anaerobic where there is a complete lack of oxygen?

[@pondguru]

The two terms are interchangeable and it's strange that people from the US generally say anoxic whereas people in the UK generally say anaerobic but the basic environment of either extremely low oxygen or no oxygen is what is needed for anaerobic / anoxic processes to occur. Within a suitable filter media or substrate it is a graded process from aerobic to anaerobic / anoxic the further into the media / substrate water travels since the bacteria present there uses up the oxygen and deoxygenates the areas deep in the media / substrate.

[@BlackshacksBushcraft]

Never used a protein skimmer. I always thought it was something used strictly in a marine system.

[@ThousandYardStare]

(my other channel) Mostly fr marine, yes. However if you have large freshwater fish eating high protein food or is they are messy feeders (e.g. Piranha) a protein skimmer can be useful.

[@edwin_cho]

Hi, can any type of form or sponge be use in aquarium? Like the form use for sound proofing? Thanks

[@ThousandYardStare]

(my other channel) While acoustic and furniture foam would work to strain out particles from the water the foam sold for indoor (dry) use is treated with flame retardant chemicals so is not suitable for use in aquariums or ponds. The proper aquarium / pond foam is not treated with anything so is safe for fish.

[@TonyElaboraziony]

Sorry i Need the name of 13kg of ball in the basket thank👍👍

[@ThousandYardStare]

(my other channel) That is the Biogravel and I have it on the FilterPro website (Biohome media page) www.filterpro.co.uk

[@gk9417]

That’s a $1000. Of media in Canada lol 😳

[@pondguru]

That is a mighty high price but I did pack a ridiculous amount in this small sump.

[@pc166829]

Hi mate...Could you do one for 5' discus tank please.

[@pondguru]

Could I do a video on a sump for a 5' tank? I don't have my shop now so I only have access to whatever I have lying around or whenever people send me as part of the PImp My Filter series of videos. The set up is basically the same for all filters - Mechanical to Biological to Chemical and a sump offers way more filtration that you'll ever need.

[@tashspond]

Aren’t anaerobic the bad kind and aerobic the good kind?

[@pondguru]

Bacteria of all types can be 'bad' when not in balance and in a well set up system both aerobic and anaerobic bacteria will grow their populations in line with the available food source. That results in a perfect cycle (0,0,0). In our own bodies 99% of bacteria is anaerobic since it lives in the gut. That is essential to our good health and it's the same situation for a fish tank system although there is a much smaller percentage of anaerobic activity compared to in a body.

[@PeterKnopp-ih8ie]

What size tank litre wise would a sump of 5his size be suitable for please

[@pondguru]

Due to the limited size, compact nature of the sump it would probably only service a 200-300 litre tank. Ideally a sump would be longer than this but the sump in this video was from a foot spa so needed to be very compact.

[@Ian-qw1zb]

I agree I never understood why anybody ever thought it would be safe to use bleach in your aquarium or media that houses living creatures and living bacteria. Let's be real bleach kills bacteria on surfaces, it contains chlorine we use chlorine remover for a tap water so it don't kill our fish. So why would you think it's safe to use on anything that's in your aquarium or your aquarium itself.. when the goal of our hobby is to grow living bacteria so we can keep our living fish alive in our boxes of water, or we could just dump some poison in there to clean it LOL not really, bad idea. Say for alternative easier to rinse off his vinegar.

[@WhizWiseRepublic]

[@muhammedhisham7658]

I just need to ask a basic question…How can oxygenated water suddenly get deoxygenated inside the sump while it pass through the biohome media…The water will ofcourse have dissolved oxygen in it along with dissolved nitrates that reach the bacteria inside and as water has oxygen how can anaerobic bacteria grown in it

always enjoy your videos. been watching for a while but usually not logged in, but finally subscribed. have a question that i can't find and answer for. understand the order of mechanical, then bio, and last chem in media order but what about the order of bio. have a sump that i am fed up with and gonna rebuild. currently using k1 and it is very effective but my nitrates are always high. although the plants outside love the when i do a water change, looking to incorporate some anaerobic media. the question is should the anaerobic media come before the k1 or after? i've spent a lot of time trying to rationalize the ratio on most products i've seen; wondering how so little would be so effective, but after watching your video i'm assuming the more the better, but with the amount of air i pump into the sump for the k1, i'm wondering if placement would even matter.

The water level looks like its a bit high on the 1st chamber not allowing much room for overflow when the pump is switched off , but for a smaller style sump it looks good 👌👍, that's the basics covered lol , wtf he's a fountain of easy listening knowledge and very comprehensive

[@stucody]

From my understanding, K1 media, and especially the micro one, is supposed to be very effective

[@gelgel85]

Hi Pondguru, I am planning to get a 5ft tank, i am getting a 5ft trickle shower filter with 4 layers of boxes. After watching this video i am thinking of changing my plan to build a sump tank instead due as it seems neater and can hold much more filter media. Planning to fill my aquarium with goldfish btw. in terms filtering capability and efficiency, which type would you recommend? also in removing ammonia, nitrite and nitrate, Trickle vs sump? And also the ease of maintenance, i believe trickle would be easier? because sump u have to tank out all the stuff inside to clean the tank where as trickle u can open the trays which is smaller and easier to clean. Really not sure if i should go with sump or trickle... help....

[@markvanderloos2422]

Is there a working setup for a 10.000 liter per hour pump, feeding a sump.

[@pondguru]

The size of the pump and the sump will be relative to the size of the tank so there's no real rules for what size the sump should be. Generally the sump would be almost as long as the tank and sit under the tank. Any 'normal' sump will give you a nation of space for all the mechanical, biological and chemical filtration you could ever need, no matter how heavily stocked the tank is - you'll still have room for whatever else you want to put in there too - (heater(s), pump(s), protein skimmer etc. The pump does not feed a sump. The pump feeds the tank from the sump unless the 'sump' is an overhead filter, then the pump would feed the sump / filter. Usually the tank would be drilled and feed down into a sump then the pump would sit in the final chamber of the sump and feed water back up into the tank. Hope that makes sense. Best of luck with the tank.

[@ziluq6836]

Hay, could you do a review on the eden 501, its a small cheap external canister filter

[@kevinjackson5033]

what is the meadia in the bags please

[@pondguru]

The media in the bags is the Biogravel - it's basically a gravel shaped form of Biohome so it's perfect for bacteria to grow on / in and has a very good accessible surface area.

[@apooch71]

[@stucody]

Are protein skimmers suitable for freshwater sumps?

[@jonmiley]

What about charcoal?

[@pondguru]

If you use charcoal it would go towards the end of the filter so that the order was Mechanical, Biological then Chemical (Charcoal is classed as 'chemical' media).

[@john-lenin]

I’ve never seen anyone test media for internal water flow and anaerobic activity.

[@pondguru]

The reduction of nitrate in a fish only system when using the biohome is down to anaerobic activity inside the media and that only happens in a 'normal' filter set up when the structure of the media allows for anaerobic activity (slow flow zones / dead ends inside the media). If you've got a specific test in mind just let me know no worries.

[@adrianrainbow4106]

Great video chief, clear and concise, and fantastically informative. I watched a few 'US' takes on this, and just couldn't follow what they were saying, they seem so intent on being 'cool and entertaining', keep jumping from subject to subject, and always start with, WOTS UP KZbinRS! Thank you, liked and subbed.

[@pondguru]

No worries and I'm glad the videos were useful as I put them out to help. I will never say "Wots up KZbinrs" - you have my word on that. Also I will never go onto Google and put in a search t erm then make a video based on the top 3 results like 99% of 'KZbinrs' do. I do not consider myself a 'KZbinr' or an 'Influencer' since things are either true or they are not and no amount of money will get me to sell my soul and parrot some crap from a company wanting me to be their 'ambassador'. That is pure horse shit and not for this channel. Welcome aboard. P.S. I will never be cool or entertaining, lol

[@ironix1]

Another nice informative video Richard. One question how do you prevent the tank draining into the lower sump and making a catastrophe? Is there an air inlet along the way to aid this?

[@pondguru]

The Tank overflows into the sump so will only feed back to the sump when the pump is working. As soon as the pump is turned off the tank does not overflow any more so the sump can't overflow. As long as the last compartment in the sump has enough capacity for the small amount of water which will overflow from the tank and other sections of the sump it will be fine. Hope that makes sense.

[@ironix1]

@@pondguru Thank you. Makes sense Richard. So the main tank must have a hole drilled to allow for pipework to enable it to overflow, correct?

[@pondguru]

@@ironix1 Yes there would be a hole drilled in the bottom of the tank and that would have a riser pipe fitted up to the water level.

If you hold pumas under water it will eventually draw water

Pumas as in the big cats? Some clarification would be good....

[@lastproductionstudio]

@@pondgurumy mistake I meant pumice(the stone).

[@ThousandYardStare]

@@lastproductionstudio (my other channel) That makes sense now, thanks - since the pumice stone has lots of sealed bubbles inside it the chances of it being porous enough to draw water into the interior is slim. You could be lucky and get decent quality pumice but since it is a natural rock every piece is different. I featured a good quality pumice in the video I did ages ago looking at different types of media under a microscope - the video is called 'Looking inside filter media' so it would definitely be worth watching that before deciding what to put in the filter.

Question about the waterpump your using. It seems like you modified the pump and connect a air hose. Can you explain how that works? Thanks!

[@pondguru]

It is a special pump designed for use in hydroponic growing systems. The air is dragged in and shredded into tiny bubbles by the impeller then spat out as a 'fizzy' water jet. They are available in 320 lph and 450 lph versions - I have them on the FilterPro site and they're available from places which sell hydroponics gear too.

[@mideviel1]

your the best nobody explains it in detail like you. they all leave you asking questions still. Thank you i have a much better understanding now.

[@mc-yt2rc]

Hi Richard, I have one of those 2 litre bottle K1 micro things in my tank. Is it doing anything beneficial? or should I get rid? Thanks.

It will be supporting aerobic bacteria and if it is 6 months old or older it will be well set up with bacteria. It's certainly not something you need unless the other filtration on the tank is minimal.

I have some here which certainly look the part but since they are held together with lime based materials they would need soaking for months to make them safe for use in a sump. I'd be well up for hearing back if / when you try one and see how it goes.

I understand that Seachem Matrix is not a good filter medium? :(

[@pondguru]

It is very hit-and-miss with the 'matrix' - sometimes it is mostly good quality and sometimes it is very poor and filled with grey rock and obsidian which isn't much good as a filter media. The unfortunate thing is that the base cost of good quality white pumice is pennies more than the lower grades so I can't understand why they don't pick the better grade which is so obviously better than the variable stuff they supply. Surely the profits on it can't be worth the lives of fish?

you forgot a uv light

[@inmotion81]

Can we get an update on the bid pond and big filter I'm really interested in that.

[@elmee96]

He already have, he changed it 😁

I miss the videos about the giant pond filter

[@pondguru]

I had an update in that long gardening video I out out recently - first chapter covered the filter.

[@vaibhavsinghtak]

Hey pondguru!! Please make a pimp my filter edition for sunsun hw 5000 and aquaone nautilus 2700uv!! Specially the aquaone 2700uv

[@pondguru]

I will if anyone n the UK sends me one, no worries - they are 2 filters I'd definitely like to take a look at.

Very informative. 👍 How do you work out the pump size / flow rate for one?

[@pondguru]

The size of the tank and what you're putting in it will dictate the size of the pump(s) in the sump and I don't know of any formula to work that out. If you have a decent sized tank 200-300 litres and would normally go for a 1500 lph canister filter pick a sump pump which will shift a similar amount.

Again, another great video Pondguru.

Glad you liked it!

Can I use a single sump for two fish tanks at once?

[@pondguru]

Yes, and that's how the majority of shop systems are set up. Ideally you'd have a UV fitted in the sump or in the return pipe from the pump to the tanks to prevent cross-contamination between the tanks. If you're operating a sump on a single tank there is no need for a UV.

[@rohithricky8275]

@pondguru thanks for your reply. I would like to watch a video on this. Could you share a video with me where a similar sort of setup is being used. It would be a lot more helpful for me before I build the setup.

[@pondguru]

@@rohithricky8275 There are a nation of videos online showing sump set ups but it is no substitute to seeing what different systems shops have set up. I'm assuming that you will be stocking the tanks with fish, plants or corals so at some point you'll have to visit a shop to pick that stock. Visit several shops and ask them to show you their sump filters and how they are linked to multiple tanks - you'll get a good idea of the fittings, pump, UV, lighting etc. etc. which you could probably see in several videos but that is nowhere near as useful as seeing the systems in person. Shop staff or owners will be all too happy to show you their systems and talk through your proposals.

@@pondguru Thanks for the info. That would be better.
