We drained our pool yesterday to about 12 inches. The water that was left was very, very green but we got most of the trash out. My husband put about 10#'s of granulated chlorine in and the water has cleared but it's real cloudy/white. My question is, do I test the water now (it's at about 18/20 inches now) or wait until it's full and we turn the pump on. We also have a bad scaling issue going on on the sides of the pool walls, I'm hoping once we get the water right it will help dissolve some of that. Advice appreciated. Thank you in advance.
