Thanks for the advice, will stop cleaning the gravel. Yes I do have a undergravel filter in my tank, they were very popular the last time I had fish.RayClem said:During the cycling process, please do not want clean your gravel. The substrate harbors significant portion of your beneficial bacteria. If you clean the gravel you will be removing a beneficial bacteria that your tank needs. Once the tank is well established, it is OK to clean the gravel, but not while the tank is new.
Do you have an undergravel filter? You mentioned a grate under the gravel? If you have an undergravel filter, it is even more important that you do not disturb the gravel this early in the process. You do not see undergravel filters being used much these days, but they are fantastic for maintaining the nitrogen cycle.
