I'm fed up with Baquacil, and want to convert to Chlorine as soon as possible !!! My water is green at this point. Just looking for some tips on the easiest way to do it, and what I need from W-Mart, K-Mart. Bleach and chlorine amounts also. I have a 16x32 Doughboy above ground, with a deep area. 15,000 gallons. HELP !!!???
