Are these Whisper Power Filter's acceptable to use? The bio filter is just a sponge that you are supposed to clean off when it gets clogged up? won't it just rinse off the bacteria?
Where is the bacteria formed when cycling a tank? is it in the substrate, water, filter, etc. or just in the filter?
Thanks.
