[/quote]Generally total gph turn over should be around 15-20 times the tank size i.e. your 55 should have 800-1200 gph total. This can vary with coral needs though. (high flow corals can need up to 30 times turnover) I'd at least aim for a 15 times turnover.
Wow! I just bought a RIO 2100 (692 gal, but 375 at 4ft) do you think this is too much for my tank? I also have 2 Hagen 50 powerheads.
I don't have any plans for corals except maybe shrooms.
