We got through last year using the equipment the homes previous owners left. A 2hp 1 speed doughboy pump and sand filter. I know for our approximately 18k gallon pool the pump is way oversized. I was looking at the pentair matrix 3/4 HP 2 speed pump. I'm hoping for an 8 hour turnover.
The pool is a 28' ag with deep center, a center main drain, return and skimmer within 5 feet of the equipment pad. I'm having trouble finding the curve chart for that pump on low speed and understanding the math to pick out a good sand filter.
