I have an ac mini in my 10 gallon tank and i was wondering what kind of filter media i should use. right now, im using 2 of the white sponges and i still have room for something else to use. also, this might be a really dumb question, the two sponges i use are on the bottom and the middle, which leaves the top one open. should i move them up or leave it as it is?
