10 months ago construction was finished on a 17,500 gallon plaster pool and 7*7 hot tub. Hired a "pool guy" to service so I would never have to worry. I begin to notice these white flakes floating around in my pool and sticking to the plaster and asked the "pool guy" what they were, he said not to worry he would add acid and clean the swg and it would go away. Flakes disappeared for about a month as I noticed the "pool guy" would add a gallon of acid to my pool every week for two months. I decided to get the water professionally tested at two locations. All recommended levels were off significantly. Fired the "pool guy" and started on whats been a chemical buying spree for 8 months. Not only have the flakes returned I noticed last night while using the hot tub there are calcium nodules all over the plaster. Family and I love the pool but it's been a pain in my you know what to keep the water right. I clean the swg every month and because its so cold I only turn it on when we use the hot tub. How do I get my hardness and Alkalinity down? What's up with the White Flakes? Any suggestions would be greatly appreciated. I'm done trying to do this myself......
Cleaned the filter last month
I just tested the water:
8.4 PH (Just added acid to reduce)
Hardness excess of 800
