A maintenance question. How should I wash the filter? I heard that the sponge in the filter harbors the good bacteria that break down the ammonia in the water. So washing the filter may upset the nitrogen cycle. Should I wash the sponge inside the filter at all? If yes, how? Like what process to avoid and what is a must. If no, why? Please explain your answers.
If you see my previous posting, I am thinking about filling the sponge filter canister with gravel instead of a sponge. Will the washing routine stay the same for gravel instead of the sponge?
