Hi, asking for a bit of advice. I've set up a new tankjust over a week ago, I have a layered substrate, co2 etc. and a few fish and a dosed once with TNC complete.
My question is, is there anything in a planted tank that can produce nitrite other than the nitrifying bacteria breaking down ammonia?
I started testing for ammonia a few days after setup and its always been zero. Then, almost just for fun I tested for nitrite and there it was, quite a bit.
I'm just struggling with the cycle happening that quickly and wondering if there's anything else going on.
Any thoughts?
