Hello, My CYA level in my pool dropped from 40ppm to 35ppm over a 3 week period, is this normal? It has been hot out here, averaging between 95 and 105 degrees for multiple weeks, so I'm sure there's a lot of evaporation. I'm using liquid instant conditioner by Natural Chemistry. It's been a consistent loss, I've lost 10ppm over 6 weeks.
Thanks, Brett
