2 Fx5's on my 180 and 2 sponge filters... Other 125 with Fx6 and a AC110. Still I need to do a few big water changes every week 60-80%. Still need another tank to spread out the fish I got though so I can lessen some of the water changes.FunWow, what kind of filtration you running there? SZ tank? Surprised it's not a sump.
