As FireIsHot said, Pentair filter bags on the outlet, and also use 1/16"-3/32" mesh screening on the inlet side. Create a large inlet to reduce clogging and low pressure areas.

Aluminum window screen wrapped over a 10' length of PVC pipe with lots of 1"-2" holes drilled all over the length, capped on one end and threaded on the other, can do well as a non-restrictive pre-filter inlet.
