You mentoned small community fish, which I take to mean tetras, barbs, danios etc. Most of these don't need strong currents, so another benefit of less water movement will be happier and therefore healthier fish.
Sorry I left out so much info. I will not be doing a planted tank. Right now I have red platys, neon tetras, cherry barbs and a pleco...which will all eventually move to the new tank. Was at the LFS and was thinking of adding some Mollys, black neon tetras, and maybe some guppys. They had alot of other nice fish but I cannot remember what they were.
So is it best to run 2 filters or just 1 with these kind of fish? Or running 2 on low?
