Any one the specifics on a rio pump (2100 - rated at 692gph)? I have heard they loose a lot of flow. This one is on my tank with a single return at approx 4' head. I want to switch pump but will be adding a SCWD in line. So I wanted to get a little more flow not less. And I know the SCWD will rob 30-50% of the flow anyway. I was thinking about switching to the QUIET ONE 4000HH (high head) PUMP 980GPH . Do you think it would be overkill?? Oh I am keeping mainly lps( acans & micros ) and some zoas and palys in the tank.
Thanks
Patrick
