My 19 year old pump/filtration system is ready to be replaced. It is a 20k gallon pool, 3/4 HP motor, 1.5 in pipe with 35 average feet of head, and other components shown in the signature below. I have read the filter needs to be rated for more GPM than the pump/motor combo even when the pump is at max speed.
Currently manually run my pump for just 2 hours a day when the water is clear.
Also, read about the pluses of variable speed motors with timers which is probably what I want but overkill?
What pump/motor/filter combo do you guys recommend for this application?
