I am replacing my dead single speed pump with a 2 speed pump. The pool holds roughly 12,000 to 14,000 gallons. There is a Hayward 400k heater attached. Is the Pentair 340042 SuperFlo 1hp, 2 speed a good match for this setup? The pump has total hp 1.25. There are 2 skimmers, a floor suction, and 2 returns if any of that info matters.
