I'm planning on switching my 55 gallon over to a matten filter and need some advice on what to use to drive it. I see many are ran with a air pump but I'm considering using a submersible pump instead.
I will be using poret 30 ppi in black. My stock is a pair of dwarf apisto cichlids, 1 small angelfish, 2 bristlenose pleco, 8 ember tetras and about a dozen Heterandria formosa. I may add one more female cichlid and possibly a angel.
If I got with a submersible, how much GPH
do I need and is one pump enough? If I sit the pump on the tank floor, will it still provide proper flow or will I need to mount it half way up?
If I got with a air pump, what size would I need? How are they even rated?
