Wow, and I thought my pool was bad............. In my case, the problem was traced to the plasterer using too much CaCl in the plaster mix (to speed up curing) and dry trowelling the final finish. Of course, the pool renovator and plasterer refused to accept the pool plaster specialist's findings and just blamed my TFP water chemistry.
Looks exactly like my problem. I detailed it in a few posts, including this one. https://www.troublefreepool.com/thr...Pennsylvania?p=1494127&viewfull=1#post1494127
My plaster is getting replaced this coming spring, under warranty. Took a lot of time working with the PB and Plaster Co., and a tremendous amount of help/consulting from OnBalance to get it resolved.

Interesting, that's pretty much verbatim what the guy who checked our pool out said - plastering deficiencies. I guess I'm just lucky that it's not too bad and barely visible unless you have an eagle eye! He said we haven't seen continously increasing calcium hardness because it was mild and only a small overall area.
Where did you find the "Plaster Professional" ?
Could I ask How much he charged for a consult?
