Water nitrite

[joão]

hi I have 5 aquarium´s with axolotls, they are all separated cause of different size , and in one of the aquarium with just one axie,I have a high level of nitrite, even after almost a complete water change, can someone help me out, and give some new tips to reduce nitrite rather than the basic ones,like less food, water change , etc...thank´s

I had this problem a while back when I changed my substrate and I think it was Michael Shrom said to put in a little aquarium salt to help neutralise it. So I did.

. I don't think the reading fell at all, but I think it helped anyway.

Have you done anything different to the tank to make the nitrite high? Sounds like maybe it's re-cycling or something.

How long has the tank been set up? How large is the tank volume? As Anne-Marie suggests, did you medicate or do anything to kill the natural bacteria that break down nitrite?

I really don´t know what it was but it´s regulating right now
