+1 to @CarlD !!!

Yeah, before spouting off I should have asked for more details on the pump/filter combo. I have a full rated, variable speed 3HP IntelliFlo pump. I also have the biggest DE filter possible. Even then, I run my pump on the slowest speed most of the time. I only use the highest speeds for quick vacuuming.

What kind of pump do you have? Horsepower? Single-, two-, variable-speed?

What's the sq-ft area of your filter and its nominal flow rate?
