i dont' know if it is the 2hp pump or not yet... and as for an inlet for it i was thinking pvc (capped) with a bunch of 1/16 inch slots cut in the bottom 3" of it, and small 1/8" holes drilled up and down its entire lenth length. what i really want is the cycles through the filter.
That sounds like a good start. You want lots of intake area to minimize the suction. Pretty much a reverse spray bar. The more holes you have in a spray bar the less pressure the streams of water coming out of the spray bar will have.
