According to the chlorine/CYA chart, if my CYA is at 40, then I need to shoot for min of 3, and a target of 5. If my CYA is 80, then I need a min of 6, and target of 9 for the chlorine. lets say pool "A" has a CYA of 40, and pool "B" has a CYA of 80, and they are both at the target levels of chlorine. If the conditions are the same for the pool usage, will the drop in chlorine be the same for each pool over say a one day period? In other words, would you have to add the same amount of chlorine to each pool every day to keep the target amount of chlorine in the pool?
