I am in the third summer of using a SWG on a new pool. The first summer I ran the the generator at 100% all summer and had good Cl levels all summer. Last year, my local pool store told me I should only be running at 40%. At the lower power, I have been unable to keep my Cl level above 1.0 ppm. They have since advised to supplement with CL hockey pucks. Does this seem like a good strategy? Will it cause any problems or level imbalances?
It is a big pool, 47,000 gallons. I run the pump 7 to 8 hours a day. I'd rather not do more, because it gets expensive. Calcium, ph, alkalinity, CYA, and salt levels are in spec and I keep them stable. I have checked the cell for scale and cleaned it with acid. Last year, I maintained with boosts and shock, but again that got expensive. My phosphates can get high, currently 500 ppb, but the water is still crystal clear and I have little to no trouble with algae.
