I must say that I usually have a CYA level in the 70-100 range due to prior puck and granular shock use. However, this year the CYA was at 30 on opening. I thought, great! Finally down. It's sitting at 50 now.

Well, I'm not liking it at all. My chlorine gets burned through almost daily, and I haven't had a huge pool party yet. I seem to be adding bleach every nite (all numbers are good, no CC's). When the CYA was in the 90's, the chlorine would hold for several days and I would only add bleach every other day or so. I am tempted to push the CYA up a bit more, but will see how pool performs this season with a lower CYA.
