So, I acquired an oscar tank with two 8 inch oscars. It is 47g (do not judge) and they have never seen a cycled tank. Both oscars have HITH and I am trying to get the tank cycled so that oscars can get well. I have media from 5 different tanks in the filter trying to support the bioload of these two guys and right now the ammonia is 0.25 and the nitrites are 0.5. I cannot get them to drop. I have 1ppm of ammonia in my tap water, so a water change will spike the nitrites. Any ideas?
