Any recommendations on a good low-flow powerhead or would I be better off using an air pump in this small tank? I was thinking of using the Hydro II sponge filter. Looks like it would be easy to move from tank to tank. Would it work effectively with an airstone?
Yes , Hydro sponge filter would work well either with small powerhead (see aquaclear) or with airstone and air pump. The powerhead would be near silent as opposed to the humming of air pump if that is a consideration.
Even small powerheads produce respectable current so if you don't mind the afore mentioned humming from air pump, then air stone and pump would be my choice.
I use Hydro sponge filters both with powerheads and air stones. they are very effective biological filtration and fair at mechanical filtration if properly sized for your application.
