| I made the mistake of building (from scratch) a 5 foot diameter x 3 foot deep vortex for 3600 gph. It was an expensive and pain-staking project which was a complete waste of time. Nothing could settle out in that whirlpool and all the leaves ended up in the little pump trap which had to be emptied daily. I threw 100 square feet of 1/2 inch woven predator netting into the vortex to slow the flow and trap debris, but the debris does not fall to the bottom of the cone bottom so it is a pain to clean. Should have made it 8 foot diameter.
