GPH, Maxed Out At Skimmer?

[nasoldier]

Does the P.Skimmer dictate how much water can be turned over. I have looked at a few skimmers and from what I understand they have to be operated at certain gph to be effective to fast or to slow would be useless. Example if a skimmer requires no more and no less than 800 gph to funtion properly does this mean that you can only turn over 800 gph? Any takers?

The skimmer has it's "own" pump (generally matched by the factory to maximize "their" design) and is "self regulating"...
But if you run a skimmer in the sump...you want to be sure to send "at least" that much water down in "turn over" through the skimmer chamber...
So the skimmer is getting new/raw water and not "reskimming" the same water over and over...
