We just got our 16 yr old pool replastered for the first time a few days ago. Leslies pool tested my new (chemical free) water and told me that I need 67lbs 8 oz of Hardness plus and also 1 quart of muratic acid in a 27,000 gal pool. They told me to put them in 4 hrs apart and told me that they were currently out of the product and sent me to anlother Leslies store. The girl at the second Leslies store told me that I would be crazy to put in more than 25 lbs because the plaster could start cracking. water test showed calcium hardness to be 50 and should be 200-400ppm, cyanuric acid showed 0 and is supposed to be 30-99ppm, total alkalinity shows 70 and should be 80-120ppm, ph is 8 and is supposed to be 7.2-7.8.

We put this pool in 16 yrs ago and always had great levels but never once used anything except for chlorine, muriatic acid once or twice and shock. I dont even know what hardener and conditioner are because I have never needed them or purchased them. Please advise me before I put the wrong chemicals in
