Wasn't sure if I should put this into here or Under Construction or elsewhere, feel free to move it.
Pool was renovated last June, new plaster, coping, tile. Plaster is KrystalKrete if it matters. I brushed and did everything I was supposed to last year, it was good and smooth and nice when we closed.
On opening, there's hard little nodules on the walls, but only below the winter waterline, and on the floor and steps (again below the winter waterline only) and it's worst in the corners/transitions where it's hard to brush. I can break it off with my fingers for the most part, but obviously I can't do that to the entire pool. My robot has also been picking up a ton of fine white... something this year that wasn't there last year (see picture).
The pH over the winter always climbs a bunch, I close it a bit extra low at like 7.4 but by opening it's 8.2+ and my CSI is sky high due to having to pump CH overboard from rains and stuff and obviously I'm not adding acid since I can't circulate it while it's closed with the cover on.
Does it sound like this is scaling? And if so, how can I fix it now and prevent it happening again over the next winter? Everything was nice and smooth when we closed and now it's much rougher than I'd like.
