Ben;

Great bit of info on the pump & filters. Thanks! If I follow your math correctly, following would be what I need for a 30’ AG pool (please correct me if I messed this up).

30’ x 54” pool: 15^2 x 3.14 x 4 x 7.5 = 21,195 gallons w/6 hr rate of 59 GPM (44 GPM @ 8hr rate)

It would seem if I went with an 8hr recirculation rate, I could stick with the pump you specified. If I need a 6 hr rate, does that push me into the SP2615X202S? Not sure I completely understand the “art” of reading the performance specs for that pump.

Some remaining questions...
• 30” filter still appears adequately sized for a 30’ pool, correct?
• Any reason not to make all piping 2” sch40 PVC and call it done?
• What is the “watts per gallon” rating for the SP2610X152S?
• How do I place/locate 2 skimmers (opposite sides of pool, within 5/10/15 of each other, etc)?

Thanks again for your help!
