It got really warm again and I want to go for a swim. My problem, I haven't yet gotten it to not drop more than 1 ppm overnight. Every day it accumulates brown dirt on the bottom that is very easy to sweep up. Is that dead algae it's still killing or dirt blowing in? What's the damage of just letting the chlorine drop so maybe we can get in another time before we close it up? Monday night it only dropped 2 ppm, last night 3 ppm. And I'm occasionally reading a trace of CC. I love to stand beside my pool and enjoy the gorgeous sight of crystal clear, beautiful water!!!! Can't get enough of it. Thanks again everybody!! So glad I found you!
