Some of us, me included, typically open to a pool with no CYA. I usually have a reading of 40 or so when I close the pool and usually find that I have none in the spring even though I open to clear water. Who knows. At any rate, it happens to several of us and is no big deal.

Glad to have you back around the forum this spring! Boy is it good to use that word. SPRING!!! I have been waiting impatiently for spring and SO glad it is finally here! Our flowering trees, forsythia and crocuses are blooming and the grass is growing. Life is good!
