This is my third season with my pool. I have a fabrico sundome and I only use bleach and acid in my pool. I keep my target FC at 2.5. I use about 8 ounces of bleach a day. The water is always clean and the chlorine seems like it doesn’t burn from the sun. Most time I can skip a day of bleach and fc is still at 1. I am reluctant to use CYA just because everything is going so well. What do you guys think.
