Aquarium Advice FINatic
I'm advising a friend on setting up a 20 gal SW tank. Having only a 90 with overflow and sump, I'm not sure what the best advice is for water movement in a 20 gal. Setting up an overflow box and sump would be too much for him right now.
I was thinking 2 MJ's would be fine but film will surely accumulate on the surface. Would a HOB power filter be a better idea?
