I want to make small sponge filters for a couple of two gallon betta tanks.
They are planted, but I think they could do with a bit of filtration and
some gentle water movement. I found these directions but I will use an
airlift rather than the powerhead.

I got some 1/2" rigid tubing and the airline. How much sponge do I need
for one betta? Would a chunk about 1" square and 4 or 5" tall do the
trick? Also, is open cell filter sponge even the best material or should
I be considering using some sort of matting? I'd like to make something
small, simple and low-maintenance.

Thanks for any ideas.
