Pros
- Industry-benchmark ProSeries laterals + 7-position VariFlo valve — built to last
- Complete kit with a 1.5 HP Power-Flo Matrix pump

Cons
- The priciest pick here (~$859) — you are paying for longevity, not flow
- Sand not included (150 lb)
- The bare 'W3S180T' tank is FILTER-ONLY — buy the complete '…93S' kit, not the tank alone
- For a true 20,000-gal-plus pool, size up to the 21-in/24-in ProSeries
“Very good unit. I went from a 1.5 hp Hayward to a 1.0 hp on a recommendation by a Pool guy. He said the power flow matrix pump was much better therefore I could drop to the 1.0hp.”— Amazon Customer, Amazon · Verified owner
