I concur. Slower is actually better, so that your skimmer has the best chance to skim the nasty stuff. Too much flow, and the stuff will just get flushed right by the skimmer's intake, without getting a chance to go through it. Depending on how your skimmer is setup, the proteins in the water column generally float upwards.
So check the GPH rating of your skimmer's intake pump to determine the flow through the sump.

Also with too much sump turnover, you could have a microbubble problem.
As suggestions, get the tank drilled for a closed loop, or go with "nicer" powerheads like Seio's or tunze streams.
