Aquarium Advice FINatic
I use sponge filters in my 5 and 10 gallon tank, and they work wonderfully for biological filtration but aren't too good for mechanical. I've been thinking of adding a mechanical filter like an aquaclear 20. But then I thought, all that nice mulm and detrious might be good for my plants so maybe I should leave well enough alone.
Any thoughts?
