Hi everyone, Over 3 months after I started my 10 gallon fish tank, I am FINALLY getting readings on Nitrites and Nitrates! It took me so long that I'm just a little paranoid that I'm going to do something to mess it up. Is there anything I should be doing with these readings? I think I just need to wait for the Nitrites to go down to zero and then the tank is officially cycled. Is that right? Here are my numbers: Ammonia 0.25 ppm Nitrite 0.25 ppm Nitrate 40 ppm pH 7.8 Does anyone have any suggestions for next step? There's been some evaporation and I'm wanting to do a little water change and fill it back up. Will that mess up the cycle? Thank you so much for any help!
