You are truelly pedagogic, the simple explanation of the denitrification process was spot on. We experimented a lot with this method in fish only marine tanks long ago. The tricky part is to balance flow to leangth of the hose. To high ratio and it dont work. To low ratio and hydrogen sulphide forms. And perfect ratio is also depending on nitrate level in incomming water. Not funny when I woke up one day and the whole house smelled like rotten eggs 😀.
What a compliment from you. Thank you! Never though about hydrogen sulphide. I guess it's important to leave a little bit of nitrate in the effluent so that sulphate is not used.
@@KoiRun50 correct. I would asume that it is easier to get the balance right in high nitrate ponds than in low nitrate marine tanks. Looking forward to see the progress.
That is really interesting and something I haven’t thought about before so am going to look at setting something like this up in my system. Thank you 👍🐟🈲😊
I'm hoping to return 100 gallons per day of warmed lower nitrate water to my pond from my flow-through system. This water would normally get wasted in the drain. It should make up a good portion of the pond volume. Thank you for your feedback.
With your massive aquaponic/bogfilter system I would strongly advice not to. In systems without plants I can see some benefits. In systems with plants I can only see problems comming.
Let me ask you this, if at the end of the hose I attach a sealed container or a series of containers and then an outlet after the last one. That would provide an increased surface area...?
Should work even better. I find my tiny hose gets plugged up too often. Slower the water flow the better. Control the flow using a valve at the end. If it gets plugged just open the valve right up to clear.
@KoiRun50 awesome. I have an old sand filter from a pool. Thinking about ending the waterhose in that so there is a ton of surface area for the bacteria to eat the nitrates. I have an elevated settlement pond that water is pumped up into and I was gonna just sink this waterhose down into that and then gravity would allow the water to flow out of it. I won't have to rely on a siphon. And there is no heat transfer issue with having the hose out in the air
I am sorry, but this is absurd. Research on wetland filtration has shown that 1m2 of sand at a depth of 120mm produces denitrification at a rate of 0.5g NO3 per day. The sand has a surface area of 20m2 per kg. To put that into context for you, 100g of fish food at 38% protein produces 26.96g of nitrate. So if you feed fish food of 5g a day the results will be 1.348g of nitrate and it would take 2.7 M2 of a sand bed filter to remove this.
I’ve read about similar studies. Detectable nitrate reduction with this tube system is when the tube is almost plugged up and the drip was very very slow. The amount of water dripped is impractical to pump back into the pond. But it was a rare time it’s ever been demonstrated. No worries and thanks for watching.
Excellent, lots of information crammed into a short video. Thank you.
Thanks Steve.
Brilliant idea/ hack. With an excellent in-depth explanation thanks Sidney. Will definitely have to experiment trying this myself!
That would be great! I'd like to know if results could be replicated. It's so simple to implement. Thanks for the feedback. Always a pleasure.

Loving these hacks Sid 😀😀👍🏻
Thanks Mike, hopefully I will be able to do an update soon.
Very interesting I shall watch part 2 with interest 👍👍😀😀
Great stuff Syd. Now you have given me a massive idea! Thank you!
Thanks Lau, Poor results so far but was an interesting one. Will have to make some adjustments.
Absolutely fascinating, really interested to see how this series develops, thank you for sharing :)
Thanks for watching Andy and for you interest.
Sydney’s a whole scientist out here! 🤣 that’s exciting stuff!
Thanks Mr Tings. I don't what I like more the koi or the science.
@@KoiRun50 they go hand in hand together 😉
@@mrtings It's no wonder I like this hobby 👌.
That is really interesting and something I haven’t thought about before so am going to look at setting something like this up in my system. Thank you 👍🐟🈲😊
Thanks Phil, It's very easy to apply. But I'm learning myself.
Great video look forward to part 2 stay safe
Looking forward to making it. Thanks Carol, you too stay safe.
Awesome mate thanks I learn something new every day off you guys 👌👍
The fellowship. We learn from each other 👍.
@@KoiRun50 definitely 👌
Very interesting looking forward to part 2 👍🏻
Thank for your support my (night owl 😂) friend. I hope I won’t disappoint 🤞.
@@KoiRun50 🤣🤣🤣 🦉
So many good videos out kept me up again 🤪plus it’s weekend 🤣
Cheers I know. I fall for that many times 😆😂😂.
Good stuff .. Interesting.. And I like it
Something different. I hope it works for me. Have a great weekend ☀️.
@@KoiRun50
Hope so as well. Then you can hook it up here.. 😆
😂 Eazy peezy, should take less than 2 minutes. Free parts and labour.
Definitely got me thinking can't wait to see part 2 👍👍👍you got dem covers orf yet
Food for though isn't it. Covers? Sorry no not yet. July 1st this year. Promise.
Very helpful thanks
Thanks for commenting 🙏
Pretty cool tip 👍
Thank you!!
Great info.
Would that work with water hose ?
In part two it didn't really work when it did in the past. I'm trying a longer tube.
very good tip buddy
Thanks Paul. Please say a prayer for me (wink).
Good information but wouldn't your pond have to be super tiny in order to reap the benefits? I am thinking like a 20 gallon pond with that size hose.
I'm hoping to return 100 gallons per day of warmed lower nitrate water to my pond from my flow-through system. This water would normally get wasted in the drain. It should make up a good portion of the pond volume. Thank you for your feedback.
Really interesting mate, might have to give this a try 👍

@@greenmachinesweden Was thinking for my indoor set-up, saw your comment about getting the balance right so might be a bit of trial and error 👍🐟
@@ecosystemkoi9159 ok, for the indoor setup it have potential to be a good solution. Didnt think about that.
That would be great! I will be so easy to implement and evaluate.
What if i used a 100 ft water hose?
You are thinking that would work? I don't see why it wouldn't.
Let me ask you this, if at the end of the hose I attach a sealed container or a series of containers and then an outlet after the last one. That would provide an increased surface area...?

Couldn't you achieve the same thing at a greater level with an extremely slow moving bog filter
I am sorry, but this is absurd.
