Thought I’d take a look back at this Andy as not watched before. At the moment I have integrated my moving bed inside my 4 barrel multi bay chamber. Think over the winter I may copy this and bring it outside after the multi bay. Will give me some nice extra filtration as I can change the existing moving bed to a static mechanical filter 👍

Hi mate, another good video. That's a good moving bed you've got there. I hope you don't mind, but I did notice when you fitted your tank connector, you put it in the hole and then on the inside added the rubber washer and nut. If you put the rubber washer on the tank connector first, then put it into the hole, it won't leak. The way you have it, water could get under the washer through the thread and cause a leak mate. Hope this helps. take care mate, Terry.

I love the video. im currently in the planning /getting the pieces together to build one . and not one of these videos talks about water flow rate. any chance you would share what's too much . currently have a 900 galon a hour pump on my skimmer. and 3200 gallons my bottom drain . pond is only 2500 gallons. and thanks for the useful information.

[@DerbyKoi]

Hi Danny when I built mine I used 1.5 inch pipe as it had a slow flow of about 1500lph it may take more but you can use a larger diameter pipe or two return pipes in the build to increase the flow rate. But as its biological and not mechanical filtration i believe it benefits from a slower flow. Andy

[@charles29cc]

So I have it prity much finished now but ran into a issue that you may be able to advise me on! So I have purchased a 8mm airline and a large airstone which connects fine however I do want a little t piece and a elbow so purchased a 8mm elbow as a test and it’s too small! Should I be using 10mm fittings to suit the 8mm airline? Can’t find much info on the web

[@DerbyKoi]

Hi mate the 8mm will be the inside diameter of the airline so you will need to measure the outside diameter and get the connections to fit that size. If that makes sense it will more than likely be 10mm but its best to check first. Let me know if you get it sorted or if i can help Andy👍

How did you combat the gap under the air disc. How did you cover the gap ?

I attached some plastic mesh around using ct1. I think I mentioned it in the video

[@LesMar-u5x]

Yes m8 did see that my mistake the EA airtube is 10mm but air disc is 8mm did it fit ok or did you have to reduce the 10mm to fit?

[@DerbyKoi]

It was a while ago, I can't remember. I think i used tape around the airstone and warmed the pipe in hot water to soften and fixed it on

[@LesMar-u5x]

Thanks m8 one last question the 90 bend going through the barrel is screw thread is that correct if so what do I need on outside of the barrel to connect to the screw/ thread bit to fit the EA pipe on cheers

[@DerbyKoi]

It's a push fit elbow bulkhead the screw part locks in onto the barrel and the pipe pushes in on both sides there is a parts list in the description of the update video.

Hi...I have 4 or 5 of these barrels and am looking at making a moving bed filter. My main filter is bottom drain to Vortex, into my 1st Eazypod, then into my 2nd Easypod then out and pumped through a 110 Watt Uv and return to the pond......So what I would like to know is, would this work off the skimmer, as I have the skimmer being pumped through an Oase 11000 pressure filter then returned to the pond...I'm thinking of making one of these and diverting the return from this to the pond via a SS blade...Your thoughts and advice would be appreciated...Thank you....Ian

[@DerbyKoi]

Hi Ian yes it would work my concern would be the water flow rate through the barrel if its to high the pipe may not cope with it and the barrel will over flow. i would consider splitting the flow from your pressure filter and having a slower flow into the barrel so it won't overflow and giving it more dwell time in media. I hope that make sense Andy 👍

[@DerbyKoi]

I use 1.5 in but mine doesn't go into the pod it goes into the returns pipe (trickle feed). I think you will need a much bigger size to prevent the pod from overflowing. You need to make sure what ever flow goes into the pod can empty to the moving bed and then empty back to the pond or either the pod or bed will overflow. Hope that makes sense

Building a new filter myself in a week or two my take on the up flow filters but holding 50L of k1 micro just getting the fittings and bit's ordered now looking around the £200 mark but easy DIY for anyone and will kick EA's bit of crap pipe thing out of the ball park

[@stevedench7781]

What does the trickle in system do?

[@DerbyKoi]

Instead of doing water changes all in one go, you trickle in the tap water over a period of time. This has the benefits of replacing the minerals more evenly, less chance of changing water parameters and saves time. You will also need an overflow system on the pond for the water to escape

[@bryanporter717]

Hi I have a similar system but mine is filled with filter matt in 1and 2 and media in 3 . I only run them for about 4hrs a day think I should run it more what is your thoughts?

Looks great! Does that a Jebao/Jecod PA45 put out enough to clean the EazyPod? I'm looking for a pump solution myself... one to run a 60 litre mixed bed (with eventual 25l ish of media) and able to switch to clean my pod... and a second pump to run my 3" jbr drain on a timer.

[@DerbyKoi]

Hi john, the 45L pump does bubble the pod, and run the moving bed, but I found out that it leaves muck in the bottom of the pod, I've switched to a 70L pump just for cleaning the pod, but from the comments I've had it seems even that wont clean the pod properly, I think there is a design flaw , I've read that some are using 120L air pumps and its still not cleaning the pod without using a brush ☹. Im thinking of a way to make alterations to the pod to make the dam thing clean properly.

Where in the system does this go?. After your main filtering or before?. For example could i put one in after the uv but before entering my filter system?. Also what do you mean by PP?. What is it?. Thanks.

Mine is after the main filtration so the water entering is reasonably clean, PP is an abbreviation for potassium permanganate, which is used for certain treatments, sterilising equipment and etching new plastic media to aid the start of biological development

@@DerbyKoi many thanks. So this is biolgical filtration and no point installing before the filter system?

[@DerbyKoi]

Yes kris, it's designed for biological filtration, the idea is. When the media is moving and bumping into each other the old and dying beneficial bacteria gets knocked off leaving room for more healthier bacteria to colonize, also increased oxygen and the movement means is virtually self cleaning 👍

[@oliverskinner8962]

On a 2000 liter pond you could get away with a 2 barrel system and instead of the first barrel use an AquaForte compact sieve (pump fed) £200 but money well spent feeding into a middle barrel of K+ don't use micro to catch fines getting through the sieve and Hel-x13 in the last barrel with Air stone and 30-45 LPM of Air depending on the size of barrel you go for. Blanket weed and K1 types of media don't mix so the sieve instead of a first barrel is an excellent idea and lots of people put that sieve In front of kockney koi multi bay filters and eazypod's fitted above dropping in.

Cheers mate, just hope the koi appreciate it 😂. I did loads of research and the helix just kept getting the thumbs up. Thanks for watching, stay safe Jobs a Goodun 👍

I'm after a similar barrel did you get yours in Derby???

[@DerbyKoi]

Hi Manda, yes got it from derby, look on Facebook market place 👍

[@Pj-yy2my]

hi would you say hel-x is better than k1 for moving bed

[@DerbyKoi]

Hi Paul, what I've researched the hel x has much more surface area and was designed to be used for moving beds. I have not used k1 so I can't comment on that, but I'm happy I chose the hel x

[@CBersPond]

Nice build 👍 Did you add any media start gel into the moving bed?

[@DerbyKoi]

Hi mate, thank you, no I haven't added any filter start yet, my water temps are still below 10c. Hopefully soon though 👍

Looks bloody awesome how much would you charge to build me one please buddy

[@DerbyKoi]

Thanks mate, it would be great if you decide to build one for yourself, it's quite a simple design and all the parts to build it are listed in the update video, I'd be more than happy to try and advise you if your unsure after watching the video. And you'll have the pleasure of knowing you built it 👍

most hole-saw bits have 1 if not 2 holes on the top side...reason is for us to prod out material tat might get stuck inside...just a tip for anyone who does not know...

hi one more thing what size did u use

[@DerbyKoi]

If you mean barrel, then 100L, diffuser was 20cm, pipe was 12mm 👍

[@marcellinemcnally3768]

Great job Andy ,but I would have put a bottom pipe on to clean it out , 👍

[@DerbyKoi]

Hi Marcelline, from what I've seen and read, a moving bed filter are self cleaning, but as you'll see I put the inlet at the bottom to cause a vortex to hopefully stop sediment from settling. I will review it, and can always make adjustments. Thanks for your comments, I really appreciate them. Stay safe 👍

[@orandaadnaro]

Excuse my ignorance but what is PP ing?

[@DerbyKoi]

Hi Pete, PP is an abbreviation for potassium permanganate, it's used for some treatments, sterilising equipment and etching new plastic media so that the bacteria can attach and colonize faster 👍

[@orandaadnaro]

@@DerbyKoi many thanks. I I've got a barrel and next I have to get some pipework, but your videos have been very useful in assisting me with planning what to do next..

[@richardfrost1026]

HI can you tell me whats ppe? think thats what you said

[@DerbyKoi]

Hi Richard, PP abbreviated, potassium permanganate, can be used for the treatment of some koi parasites, also good for sterilising used media and helps new media to colonize bacteria quicker

[@etgar]

@@DerbyKoi Can you tell me the concentration of PP you used to prepare the new media and how long you soak it? Also do you run your air to circulate the balls while soaking? Thanks so much for this video - I'm acquiring the parts to make mine now - 8^)

[@DerbyKoi]

Hi mate, if it's just for sterilizing the media, there's no persific amount. Put enough in so it turns a dark purple and aerate for 24hrs if the water does start to turn brown, just add more pp and remember to neutralise with hydrogen peroxide before adding to the filter.

[@davidneil1452]

just looking at filter media whats P P ing

[@DerbyKoi]

PP is an abbreviation for potassium permanganate, it's used for certain pond treatments but be advised it is very dangerous if instructions are not followed, it is also used to sterilise old media, it also has the advantage of etching some new media so helps to mature quicker.
