Eheim canister filter 2213

[Orca2013]

Is Eheim canister filter 2213 good enough for my 240L/64G ?
I will have around 30-40 fish. Most not bigger than 3cm.

I've got the 2215 on my 29G (with their spray bar kit with extra extensions so the current isnt too crazy). So while the 2213 should work for your tank bio wise, having small fish and all, the extra flow/mechanical filtering the 2215 will give would be better, and shouldn't create too crazy of a current on a tank that size.
