anyone here use it?
any suggestion to it?
and the biological filtration seems pretty cheap..it's just a piece of "foam pad"
since my other filter had some rocky things in it. is foam actually going to be enough biological filtration?
i thought i could add some of the biological rock things into the whisper in-tank filter, but if i do that will the filter break?
