A few years ago we had algae problems, despite keeping the chlorine up, and thanks to this pool forum(no help from Leslies) it was determined that my CYA levels were really high. Problem was solved over a couple years, running the chlorine levels high, getting a good test kit and gradually diluting the water.
Fast forward a few years, and darnit we did it again! We started getting some algae in spite of good chlorine levels and I tested the CYA today and sure enough it was about 100. A few months ago it was at 50. I didn't realize the pucks my husband bought from a coworker(with a pool biz on the side) contained CYA. I know how to deal with it this time, but my question is:
What is the purpose of the trichlor pucks if they keep adding CYA to your pool? I use bleach, but we keep pucks in the floater as well. Not any more though!
