I have an above ground 21/43 oval 4' depth My pump is a Hayward 1.5 hp Hayward-Flo Matrix. Filter is a Hayward Perflex DE EC 40 (rated 40 gal flow rate)
I've had this for several years but now I'm wondering if I could replace the pump with something that is quieter and a lot more cost effective to run. My electric bill gets very high with this thing.
Not sure if this filter is big enough for a 21,000 gallon pool. Seems that the water in the far end doesn't mix very well.
They also sold me a 200,000 Btu heater, which I'm not sure is big enough.
Live in N. IL so its only used for about 3 months, so I'm not sure I would save much with a more efficient pump.
