Hi, I had great luck this summer keeping the pool clear and balanced. But since it has turned cooler here in Dallas, TX, the CC has rarely been at zero. It has been 0.5ppm or less (just barely pinkish color) We went out of town for the weekend, so I put in some extra chlorine. The CYA is around 30, it is about a 26,000 gallon pool. The FC tested this morning at about 5, but the CC is 1. Why is it going higher, the pool looks clear? We did have our back fence re-stained last week, they did cover the pool, and I had the pump turned off for a day. I normally have the pump running for about 5 hours a day.
I brushed the pool down several times last week, do I need to do more, or just slam the pool?
