I would say a single 2217 is good up to 55 gallons or so, yeah it's rated much higher than that but I never go off those ratings. The turnover rate on it isn't really extreme, my tank has decent flow but it's nothing that disturbs the frogs. The plants in my 40B are so dense now I can't even see my frogs unless they come up to the front of the glass (I need to start pruning..), lol. That slows the flow down consideribly.

It's not like I put a Fluval FX5 on there or anything. =P
