New at this. My chlorine levels seem to drop too fast, using 6% Clorox bleach from Costco and recommended amount from the calculator web site recommended here. Chlorine levels stay good for a day or two, then drops fast. Poring in 2-3 128oz bottles per week. Please advise!
History: used chlorine tablets for several years until discovering this site. Pool has always been crystal clear and still is.
