I am wondering if others in the Houston area ever have issues maintaining CYA levels UP. For years I've cared for my pool with the BBB method and it has always ran low CYA numbers (I've always had to add as needed). So this year I tried something different. In January, the CYA was pretty much non-existent, so I decided to start using TriChlor tabs as the sole primary source of chlorine. However, the levels never climbed up like I thought they would. Here we are, six months later and I can still see the dot at 30.
The weather has been crazy- much rain to high temperatures in a matter of days. The pool did overflow on one occasion but I don't think it was significant enough, plus the CYA levels never were over 30. I am not necessarily complaining (I know the problems that come with a high CYA), I'm just curious as to why this is happening.
