Testing for nitrates in qt??


New member
I'm sorry if this is a topic that has been covered before but I spent all morning searching for the answer. I know that copper throws off liquid tests for ammonia but what about nitrate test. I have an ammonia alert but my qt is a cycled tank and I need to test nitrates. Any info or links to info would be appreciated.

Is the fish "tripping"?

I wouldn't worry about the nitrates. Elevated nitrates IMO just means the biological filter is working eXtra hard to break even with the bioload. When the filter "cracks" so to say, ammonia will be on the register.
