Thanks WaterMom, Should I add more bleach to get my cl level up then retest for CYA? Then if my CYA still is too low do I go ahead and add more? I don't want to risk getting too much but I don't think I have enough yet.

I have been adding bleach and my level does go up but it is eaten up rather fast and hard to maintain a higher level. Is this because I don't have enough CYA yet?

Thanks,
Klondrie
