Hi
thanks for the quick welcome! I haven't a clue about calcium levels or CYA. We have a test kit from the pool company that has 5 bottles and I don't believe they test for those things. We use it to test for chlorine, ph and total alkalinity. I'll have to look into getting the better kits you recommend on this site. I don't know what my closing levels were as far as CYA because they don't test for that at closing.

I'll check our chems' ingredients for calcium and reply back on that tomorrow.
Thank you!
