Purchased liquid CYA for the first time. Bought at local Leslie's. First of all, she did her best to get me to buy pucks instead. She said I would have to be adding chlorine all the time just using the liquid (I actually just bought the bleach, didn't tell her that). When I told her "but if my CYA gets too high, then I am stuck", she quit pushing them. In any event, out the door cost of 1 gallon of "conditioner" which contains 35% cyuranic acid was $40!! Says it will get me up to around the 50ppm for my 10,000 gallon pool. Please tell me I won't have to add anymore the rest of the year!! I just had a new liner installed, so I am starting w/ fresh tap water. Did I take it in the bunghole from them???
