I was so impressed with the water clarity and feel after shocking with bleach for the first time that I have to give a "shout out" to Trouble Free Pool! I do believe that my pool was never shocked correctly using trichlor shock, as it has NEVER looked like it does now. I shocked 2 days ago with 7 gallons of bleach (CYA is in the neighborhood of 80, waiting for more evaporation to do a partial drain-down), and my levels 2 days later are FC 11.5, CC.5, TC 12. I swam in it last night and the feel of the water has dramatically changed from a dry feel to a softened, luxurious feel. Thanks to everyone past and present for input, solutions, problems & work-arounds. TFP rocks!!!!!
