- In this video, we cover that the need for an aerated bottom drain is usually unnecessary and an overrated expensive piece of kit most koi keepers ponds.
We also cover the fact too much or supersaturated water can lead to Gas Bubble Disease. - แนวปฏิบัติและการใช้ชีวิต

Thanks for this video it has opened my eyes to a lot of misinformation. I made all my own filters for a third of to the price of the equipment I was quoted I'd need. Love koi keeping it doesn't have to be expensive. People like yourself are so full of really honest info, thanks again really liking the contents watching some of the backlog videos take care keep the contents coming cheers
Thanks Gary appreciate it!
Found this video really helpful. made changes too my pond as a result of watching and couldn't be happier. shared you video with my followers to help us all. keep up the good work matey
No probs, if a fish has evolved over thousands of years in low oxygen water basically means they don’t need that much o2, just don’t over stock and over feed they are the easiest fish to look after. Thnx for the comment
Great information thank you,I’m building an in pond at the moment kidney shape 3and a half foot in the ground plus 2ft out of the ground around 4ft at its widest point and around 11 foot long,I am going to put a liner in ,and have plants all along the length I have a2000 Lt p/h sun sun bio filter will that be sufficient if I run it through the plants and back into the water to keep the water clean?also what is the best way to get the waste out of the bottom?.
Just discovered your channel, and your advice goes against pretty much everything else I have heard or read, lol. Thanks for your honesty, I was in danger of going down an expensive and incorrect path
thanks for the comment. most advice in this game is linked to some sort of product you dont actually need and everybody just believes everyone elses rubbish. We arent trying to sell anything we just say it how it is
Thanks for a great video. What's your opinion on aerated BDs drawing water/waste towards the BD?
Hi George, I would say that any “current” moving away from the drain is lifting the dirt towards the surface rather than the base where the drain is. I know eventually the debris will make its way in the bd but that’s thanks to the pull from the pump. Effectively it takes longer for debris to enter the filter. Cheers thanks for the comment.
@@thep0ndman thank you for your opinions generally. They're often slightly unorthodox (which I think tickles you🙂) and I like that fact. It opens the mind to various theories and what is possible when ponding!
When i built my 12,500 uk gallon pond, i made it 10 feet deep with 4 bottom drains running into 2 RDF's which then flow over 5 sets of bakki showers. I have one aerated bottom drain, after it had been running for a few months i noticed a few of my big girls acting up. After some investigation, found out that over 6 feet of water the compressed air has nitrogen in it and that really messes with the koi, i lost 2 of my big girls before turning off the compressor. Since turning it off, no more issues with any of my koi. Thanks for your channel and the work you put into it
Wow 10 ft deep I bet that took some digging! Shane that you lost them and yes fish can get the “Benz” like nitrogen in water and different changes of water pressure, gas bubble disease not good for them! Thanks for the comment appreciate it
@@thep0ndman If i had known that my bakki showers were all i needed to supply oxygen to the pond, i would never have bothered with the aerated drain. I lost two good 95cm koi over that issue. As for the digging, it was all carried out with a 20 ton 360 komatsu, took less than a day, it was the massive pile of dirt that took the time to get rid of :-)
you take care
I’m building a koi pond around 5000ltr. I’ve watched your videos on pipe work so would 2 inch bottom drain and pipe work be ok. As I know 2 inch pipe moves around 15000lph. I deffo think a 4 inch is massive overkill and will make it stagnant.
Hi Adam. Thanks for the comment. Yes a 2inch would work. You prob would only need an 8000 ltr per hour pump for a 5000 litre pond. If you use 2” pipe just bare in mind to how far your filters are from your pond and how many bends to reduce friction etc. so less bends and as close as possible. Il
What test kit would you recommend for testing oxygen levels in our pond? Thank you in advance for your time.
Also I’m new subscriber, my husband watched your video on filters. Very informative & resulted in us having to buy a new filter, because we didn’t have an adequate one. So thank you so much, wish we had discovered you before we bought our first filter. Have a great day 😊😊
Hi thanks for the comment. With regards to o2, as long as you have half decent water movement or surface disturbance and normal fish stock & silt levels your o2 levels should always be fine for standard pond fish (orfe and sturgeon require slightly more o2) o2 is prob the least tested but for peace of mind you can buy a basic test kit like this one:

@@thep0ndman thank you for taking the time to reply
What's your opinion on venturi in the pipe work ......cheers
Hi Barry. Probably not needed if your filtration system and pipework is already providing enough aeration and if your not keeping trout, barbel or fish that require high oxygen levels. Tbh a bit of a gimmick with a cool name
Good, that's something else I don't need to buy. Thanks for another great video.
Our pleasure!
Interesting. I keep Carp, Koi, Tench, Orfe & Sturgeon all in the same pond. My bottom drain air pump failed once, in November, all the fish seemed fine except the sturgeon. After about 24 hours they seemed to be up near the surface and nearer the waterfall more than usual. Behaviour returned to normal once fixed.
I’ll certainly get a test kit to check this out though I don’t believe my levels are too high for any of the fish, but perhaps too low for the sturgeon if not running for extended periods?
Sturgeon naturally come from higher oxygenated water. Large fast flowing rivers in Canada so they would be the first to be affected. Carp/koi don’t mind less aeration but other species may need more. Thanks for the comment
Thanks for comment. They certainly can live in higher levels but they don’t need it. They can survive at 1mg/l, 2 ideally. Btw koi are just carp, high stocked ponds/tanks may need more but not as much as you think
Hi, another interesting video, I have never felt the need to use an air pump to aerate my koi pond all water returns from above water level this breaking the surface and aerating the pond. Also have have moving bed which is heavily aerated and move approx 20000 litres an hour on a 3000 gallon pond
Yes that’s ideal really with all the water returns. I think most of the time you can visually see all the aeration going on with all the water movement etc. thanks for comment sorry for the delay!
@@mangorambo1557 True enough but a tad different to having one directly in the pond. I have air directly in the pond currently after adding chemicals and probably will leave it there
Excellent video, I have a nexus 320 with 130lt air pump for a bio side, will that be enough for 2000gal pond, well said can you do more video's like this, I have koi
Hi Mark yes that should be fine. The saturated air will make its way to your pond through the pipe work! Happy fish
Thanks bud for the video.
No problem 👍
Might be a good idea not to put any air pumps in a pond. And I do agree with you on people going mad on aeration.
I keep goldfish and have 2 airstones in the pond (2500-300Ltrs) and one airstone in a KK KV5000 filter (in the alfagrog bays). There is a 4th stone in the wildlife puddle all running off a Hailea ACO-208 or 308? I have a 6 way valve on it and apart from the summer I leave 1 tap venting to the open air (closed in extreme hot whether.
Some ponds won’t need additional airpumps depending on their set up in regards to water flow / movement / splashing. Is worth keeping an eye on oxygen in summer. Thanks for the comments!
Thanks man, saved me some higher electricity bills. Pond pump + filter but no need for airstones.
Glad I could help
I don't run aeration in my pond, i use the electricity to pump water through the filter instead. It will let more air dissolve into the water by simply flowing more water.
Sounds ideal thanks for the comment
I think some one recently tested a bakki shower hand had less oxygen coming out than going in.
Thanks from the comment. Doesn’t make sense but please explain for everyone cheers
@@thep0ndman if I recall they reckoned the bacteria was feeding on the oxygen and taking the oxygen out. It might of been wrong but in theory makes sense. I haven't got one so can't test myself.
@@HEDST8 That’s my understanding too, the process of Ammonia to Nitrite to Nitrate in the filter consumes the oxygen!
My filter chambers perform significantly better since I started aerating them, improving my water quality massively!
I think the air-rated bottom drains help to move water around and draw waste towards the bottom drain
in my koi pond I only keep chagoi but people said that weird
Love a chagoi! The friendly koi thanks for comment
Great, but this comment has nothing to do with the subject of aeration.
@@mirola73 well it didn’t have to be
Koi carp come from ponds, lakes and rivers. The Japanese say their foundation stock originated from river carp….. So maybe this is why many use air pumps and stones in their pond….
Thanks for the comment. Koi are just carp, they do not require additional aeration if your filters and pipework can supply enough which is usually the case.
Too much oxygen? Said no one ever!
Gbd ☠️
holy Christmas this is absolute rubbish! Been keeping koi for over 30 years and never had it one single problem with over oxygenation LOL hilarious.
@@mangorambo1557 exactly!!!!
@@mangorambo1557 not possible!
It's nearly impossible to saturate water 100% with oxygen unless you start forcing pure oxygen in with cylinders.
Koi don’t need half as much aeration as people give them it’s un-natural that is what the video is about
What you mean is 'dissolved oxygen' in the water. Cold water holds oxygen and warm water depleats oxygen. Moreso, you are pumping ouside cold air into the pond further reducing the temp. So yes, in winter, it's pointless having the air pump.
thanks for the comment
