Okay so, I have a 1lb pet bass and bluegill. In a 55 gallon tank. And I put them in it because I knew they were pretty hearty fish and I knew I could do the nitrogen cycle which I’m not really familiar with with them in it because I caught them from a pond. I have a few pictures of the test that I just did after 55 to 60% water change and I’m not really quite sure what to do. Have had the tank going for a couple weeks now. And I have a heater and two filters going. I feed them about 10 medium goldfish a day. And I only have black sand in the bottom. Not quite sure why my ammonia is so high. But I need all the help I can get.
