OK, I got the sequestrant and everything seems to be going well. Stains seem to completely be gone. It has been six hours. I put my dolphin in to get the dirt off the bottom and we will be turning the pump on with the filter. It has been recirculating just the water so now I will put the filter in. Run pump 24/7 Tomorrow I will start to rebalance the water with baking soda and borax and then chlorine liquid and test frequently to keep ph at 7.2 or less and FC /cya balanced. I had a lot of trouble with CYA being very high last year based on Leslie‘s so I bought my own kit and got it down to 50. Our pool man did not want to drain the pool because we have a high water table and there is always water behind the liner unless we have a long dry spell, I spent most of last summer draining the water and refilling it even though I was told that it’s not the correct way to do it somehow over the three months it did seem to go down as long as the CYA is reasonable when I test it tomorrow, I think I will be in good shape getting the rest of the water balanced Thank you for your help. I struggle with this because my husband doesn’t trust. I know what I’m doing and wants to jump ahead and just dump the chlorine in so it has been a battle.
