I noticed upon a week ago what appeared to be a white build up on the side of my pool wall below the skimmer, did not think much of it, but now I'm starting to see a few of them throughout my pool. They appear to be buildup of calcium scale, but they are hard like little rocks I can feel them with my net when I go across them on the bottom scooping up debris. I have always tried to keep my water balance, the pH did get a little high, around eight a couple of times, but nothing too high. I will attach a couple pictures. You may have zoom up you'll see the deposits I am talking about. There are two small deposits right where the trim rock meets the plastered wall on a ledge, the other ones are on the bottom of the pool with the exception of the one right below the skimmer.
Current numbers are:
Ph -7.6
C- 5
CYA-60
CH -600
TA-120
Salt - 3200
Borates - ~30
Temp~70
Water clear
Pool re-plastered about one year ago.
If my pH got a little bit high, I've seen scale precipitate out but never form nodules from the pool surface. Is this a problem with my plaster?
