the only thing I can really think is water level.... It is an insump skimmer and currently the water is 8-10 inches deep. The water level cannot get any lower then 6 inches. What would be the appropriate water level for this skimmer?

I have a 280 and I run it in about 61/2" of water, I heard through another blog that they run better at the lower end of the water level scale
