Nitrate In Ponds | Koi Talk | Ep  

Lovely video again!

Great to look back at these pod casts guys. This week i have been panicing a bit about really high Nitrates. I have been feeding hard on Saki Growth for 3 months. Heated to 24 degrees with Amonia at 0. Nitrite at trace and Nitrate at about 80/90ppm. Now watching this back again it puts my mind at ease as the koi are loving life. So thanks Koi Talk. You make pond keeping easier with helpful advice!!👏👏👏👏

Great video Ricky I must admit nitrate is the last I check and is not something I've ever really suffered with but it isn't something I would want in my ponds at a high level for a long time but with the right media and right filtration it's quite easy to keep very low maybe not 0 but on a Colombo test that says I have 0 so that does me 👍

Morning all, on a Mediterranean beach watching koi talk, does not get much better

Love the auto focus on the microphones 🎙 haha

You are absolutely right that most people do not put more emphasis on dissolved oxygen level. To me, that is the most critical aspect of a koi keeper if they want really good big healthy fish. This is the reason why bakki showers work well, it's not the media, it's the water flow being broken up and absorbing more oxygen. People should do everything they can to flow water and have it break up into more droplets to get more oxygen. Moving media bed filters nowhere close to being as good.

Brilliant episode. Thanks from Denmark. 🇩🇰

Could the zinc in the water be from zinc parts and zinc plate jubilee clips on pumps and hoses etc on those types of ponds?.....i feel like it comes over from the tropical fish hobby in regards to algae growth

Hi guys where do you send your water samples too for a full report, I couldn’t see the link you mentioned? 👍

TY

In fact, you're detailing things that are hardly ever on the agenda in Japan, and you're all responding to that, aren't you? It is simply a matter of course that if the density of KOI is high and you feed them a lot, numerical values of nitrite concentration will increase. How to control them comprehensively? is in accordance with rearing in mud ponds. How to get a sense of them is a top priority for all of us. So I've said it many times, you never see Japanese hobbyists with test kits in their hands, do you?

Great stuff guys very interesting, cheers 🤣

Can Nitrate levels be too low?

Very interesting talk as always but I will have to disagree there about the nitrate being harmless. It's not toxic but it can be harmfull at high level for long periods. Especially for the pond keeper where fish more or less live in the same pond for years or even forever. Unbalance between nitrate and phosphate can create problems with string algea. It's not a parameter that should be ignore all together I feel. I am not too worried that my nitrate is now at 15mg/l, but I do use a nitrate remover resign to at least reduce the nitrate from the tap water going to the pond when I fill back in after a filter clean. 40mg/l in my tap water is not something I like, so not keen on this adding nitrate to the pond.

Good video. But while i agree that you should be worried about all other levels and aspects first i have to say i disagree with a blanket nitrate is not a problem. Its a known fact that high levels of nitrate in drinking water transfers into the human blood stream, high levels of nitrate in the blood inhibits the bloodstream ability to cary and transfer oxygen. I think its safe to say this would be the same for most animals and fish. There is also the saturation point where the water can not hold any more nitrate. Im not sure of the exact figure but its around 400 to 500 ppm. At this level your nitrobactor will find it hard to convert nitrite into nitrate. So there is a level where nitrate becomes a real issue. I personally dont like to see my nitrate level rise above 50 ppm and aim to keep it below 20. This also avoids the dreaded green water algae blooms in spring. I use ozone treatment which also helps keep nitrite at zero. Im heated so my fish never have to see below 14c and i use ion exchange media to pull out the nitrate as ive been unable to get bacteria to do it as of now. The ion exchange puts chloride out and the ozone breaks that down and gasses it off. Its a balance but it is doable and at reasonable cost. Ofc smaller ponds it costs less. My pond is 66000 ltrs

6x Feeds a day all summer still have barely any nitrates to me it seems like nitrates take forever to build up especially if your using high quality food

Been preaching this for years. Nitrate being harmful to fish has been pushed by the industry for decades. All to sell products that facilitate water changes. Nitrate is not the boogeyman it's been thought to be. Drives me insane when people say 40 ppm is too high

👍🏽👍🏽👍🏽

There are a lot of urban legends about all aspects of fishkeeping, my very personal opinion is that high nitrates may or may not be a sign that there is also other forms of waste in the water

👍👍

Look forward to this 2.5hrs journey.

I don't bother very iften to check NO3, I do check O2 (first thing in the morning) with a JBL pro liquid test, without the air pump overnight it would drop from 8 mg/l to 3 mg/ - probably because I have lots of plants. Seems accurate enough for what I need, I have Hanna checkers for other tests but as Ricky said good digital meters are expensive and temperamental

Fascinating stuff, always is. Between you I’m improving my koi keeping skills, so thanks for sharing. Stay safe and well 👍🏻

Great advice Ricky love the channel

Sorry Ricky, here my pond water is at 29° and my fish would come out and slap me if I did not feed them every two hours

Another quality addition guy's saying it as it is , you have the credentials to back it up not like a lot who frankly waffle bollocks!! All this info you have been putting into the public domain in only helping hobbyists and that's what it's all about .

With regards to water changes, it might be worth some of your viewers to watch DR Novak videos on here, he’s had tanks for 10years plus without water changes mainly due to anoxic filtration. Definitely worth a watch and great educational stuff, keep up the great work guys, great videos!

If you want to grow large koi fast, pump in 97% oxygen from a concentrator
