I have a 1.5hp pump and figure i'm turning it over 2 times a day with 12 hours run time. M y wife likes the pool "on" whe she is at home as it also runs the fountain. I might cut it back to 2 5 hour cycles and see how that does. I'm just amazed at the low output I need to maintain 5ppm FC. once again....Thanks!
