re: Pool Owners step inside

1) Very rarely, usually after a long period of no rain and feel the need to back wash sand filter
2) Never
3) Never


I have a fiberglass pool with a dial chlorinator set at 2 to 3 ppm and a UV light. I spend about $250 a year on tablets and about $50/year on borax. I test the pool pH once a week and add borax to raise it as needed. My pH typically drifts down with time.

Been a very easy and relatively inexpensive system.
