So, I just bought a 6 gallon JBJ about a week and a half ago from someone who had it up and running for about 6 months. It has live rock, sand, 2 clowns, and an anemone. No other corals. I just tested the water tonight and my nitrate levels were about 160. Nitrites were basically zero. Do you think it might be going through a cycle from the move? Should I let it cycle or do a big water change? Want to get the nitrates down before I add anything more.
