This was a fantastic explanation of nitrification and denitrification! I've been using anxious filtration for the past year and it works wonderfully, but I can never really explain HOW or WHY it works. Very helpful.
Wow, I went through many videos of people and experts explaining anoxic and anearobic but none made them so clearly understandable like yours. You made a gem with this video.
Hi again Jay, I have to tell you that I have spent two years watching videos on anoxic filtration and none of them even come close to explaining things as well as you. It took me months to get my head around what you just explained in ten minutes! Well done!
what is the type of the bacteria that breathes using nitrogen in the anoxic condition ? can we add the bacteria from the outside manually to speed up the anoxic filtration ?
This is excellent biological science revision and so well presented, nice and slow. Never uses the 'errr..' expression! I do run your videos at 2x normal speed though.
Thank you so much for this info. Unfortunately even though you do the best job yet explaining this, I have to keep replaying it. I am an avid viewer of this info. and your site. JP's wife
Maybe I missed it, but what carbon food source do the Facaltative Anaerobes breathe NO3 to consume? What is an example of the carbon in an aquarium for the denitrification process?
Jay, your knowledge is invaluable and your lessons are amazing! Thanks so much! Do you recommend any sources/books I can read to further understand the principles of the aquarium ecosystem?
when there is no free oxygen available in the water the bacteria has to turn to the oxygen that is tied to the nitrate molecule. That's how denitrification occurs
Watched the whole series and loved it. You mentioned adding carbon sources such as alcohol to feed bacteria. In addition to N2, could these bacteria produce a significant amount of CO2 usable for plant growth?
Can denitrification be achieve even without any dosing of carbon source? Ive read somewhere, that there are these type of bacteria (facultative bacteria) which does not require carbon dosing.. any thoughts on this?
An important question: What do you think about Dr. Kevin Novak's invention; anoxic filteration with kitty litter to pull pozitively charged ammonia inward then produce N2 as a waste? Technically, do you think it is true?
Hi Jay, it might be to early for me to comment as I am only on part two of your video but is this not how canister filters work? And what is adding the oxygen into the tank for the fish?
Hey everyone, I was wondering where the hydrogen is going on the first step when converting ammonia. Does it turn to hydrogen gas and bubble away? And if it’s being consumed by the bacteria wouldn’t it be part of their waste?
If we want anoxic conditions, why do all the aquarists push to make sure we have water flow/surface tensions/air bubblers. I was under the impression that these help with the nitrogen cycle because they add oxygen to oxidize?
During the process of nitrification, hydronium is released increasing pH, then plants will absorb the hydronium through ammonium and hard water plants will also absorb excess hydronium by absorbing hCO3-
I understand the need to provide some background information but I really feel this entire series could have been done in a single 15-minute video. The first eight minutes of this 11.5-minute video was background information that could have easily been skipped without overly compromising the big picture. I still have to watch Pt 5, but I'm hesitant to do so. I really don't want to sit through eight minutes of talk about photosynthesis, root growth, and other biological trivia in order to find out if there is a preferred methodology for selecting plants for a tank in the last three minutes of the video. I'm not trying to be mean. You clearly understand the subject and you present good information. I'm just saying that when somebody clicks on a video about how to drive a car they don't want to watch ten minutes of the history of the automobile first.
_Replying on old comment..._ Think of it as those book named "xyz for dummies". These videos basically it. And I think you aren't the target of this video, just saying 🤔
@@helloaldrian Even the target audience didn't need much of what was presented here. Some of the information simply wasn't necessary to accomplish the task at hand. It wasn't bad information, just superfluous.
Anaerobic = total absence of free oxygen (O2) or bound oxygen (NO2, NO3) Anoxic = absence of free oxygen, but presence of bound oxygen. Hypoxic = low oxygen
Why are Jay’s video not getting the views and attention it deserves?! The explanation is spot on and easy to understand!!
Thanks I think youtube algorithm prefers non educational fun videos.

Have been looking for proper explanation to anoxic condition and the underlying chemistry.Hats off Jay.
Hi again Jay,
I have to tell you that I have spent two years watching videos on anoxic filtration and none of them even come close to explaining things as well as you. It took me months to get my head around what you just explained in ten minutes! Well done!
Glad to inform :)
I'm the same, he's a good teacher, cheers from scotland 🏴
And also, videos that came after Jay's, right? 👍✌️
Most technical aquarium youtuber !! Best content,thanks for those valuable and précise informations
The greatest explanation over the network
this is the 2nd time watching this series, before I set up my 10g planted tank w/ Betta. Shrimp, and Ramhorns.
you just became my favorite aquarium youtuber!!!
Greart lessons.
Cheers from Spain !
what is the type of the bacteria that breathes using nitrogen in the anoxic condition ? can we add the bacteria from the outside manually to speed up the anoxic filtration ?
You’re videos are incredible. I am building a nitrate reactor now. I will let you know what my progress is.
Waooooo how simply explained ....gr8

These videos are great.
That was excellent. Thank you
do you also create chemistry videos? i would watch them...you are a great teacher! thanks for the series
Love these videos keep doing it
Good video
Love this
This is gold . Thank you

Amazing video thank you
Don`t plants consume no3?
yes
Watched the whole series and loved it. You mentioned adding carbon sources such as alcohol to feed bacteria. In addition to N2, could these bacteria produce a significant amount of CO2 usable for plant growth?
Where are you located Jay?
Thank you
Can denitrification be achieve even without any dosing of carbon source? Ive read somewhere, that there are these type of bacteria (facultative bacteria) which does not require carbon dosing.. any thoughts on this?
Carbs in fish food can be food for the bacteria as well. If fish food is not enough then you need to dose
An important question:
What do you think about Dr. Kevin Novak's invention; anoxic filteration with kitty litter to pull pozitively charged ammonia inward then produce N2 as a waste? Technically, do you think it is true?
Hahahahaha "and this guy (O2) is crazy¡¡¡"
So how do you eliminate the production of oxygen, stop the wave maker fan?
GREATvideos!!
GREAT INFO THANK YOU
Hi Jay, it might be to early for me to comment as I am only on part two of your video but is this not how canister filters work? And what is adding the oxygen into the tank for the fish?
Commercial canister filters wont get rid of nitrates
But if we reduce the flow into the big canister to create anoxic conditions in?
Hey everyone, I was wondering where the hydrogen is going on the first step when converting ammonia. Does it turn to hydrogen gas and bubble away? And if it’s being consumed by the bacteria wouldn’t it be part of their waste?
So the question is how to provide carbone for denitratification to be effective ? ( except ethanol or acetique acide ) ?
Dead roots of plants is what im thinking
If we want anoxic conditions, why do all the aquarists push to make sure we have water flow/surface tensions/air bubblers. I was under the impression that these help with the nitrogen cycle because they add oxygen to oxidize?
you never want anoxic conditions in the tank. you just want it to happen in the substrate if you aim for denitrification.
Wow I think I want to study chemistry now
Isn't "Anoxic" means very low oxygen?? Lower than 2 ppm
Not sure if there is a specific definition such as below 2ppm. I believe the term is used more generally to describe low oxygen environments.
Doesn't the release of N² will change the pH in some ways?
no
During the process of nitrification, hydronium is released increasing pH, then plants will absorb the hydronium through ammonium and hard water plants will also absorb excess hydronium by absorbing hCO3-
would facultative bacteria if there was oxygen also produce nitrate ?
no
thx :)

Anoxic means low oxygen, not zero oxygen.
Anaerobic anoxic and aerobic are all significant of a proper biological working substrate in an aquarium.
not correct - jinjonh the chem guy,
A means NO! A thiest, means No God
Anoxic is no oxygen. Hypoxia is low oxygen.
Anaerobic = total absence of free oxygen (O2) or bound oxygen (NO2, NO3)
Anoxic = absence of free oxygen, but presence of bound oxygen.
Hypoxic = low oxygen
Not the best anime I have ever saw. lol
