For a 22' x 52" Intex above ground ultra frame pool, 10500 gallons, 18" Sandman sand filter holding 110 pounds of sand, Intex SWG and through the wall skimmer in South Carolina. What would be a good choice and size of pump? The 18" Sandman when sold as a package with the pump, includes the 1 HP Swim Time maxi pump NE6151B. Wondering if a 3/4 HP pump of another brand might be a better choice of pump or a 1 HP of another brand would be better to look at. Perhaps a 1 HP or 3/4 HP two-speed should be considered.
Wondering about a Waterway HI-Flo or Waterway Supreme?
If converting the pools original water outlet to the pump (used before adding the through-the-wall skimmer) into a second pool water return, that may increase water flow back to the pool and be another item to consider the pump size?
