I got my pool replastered at the beginning of the season. Over the last 2 months the calcium readings have slowly risen from 250 at opening to 525 as of this week. Besides pH levels which rise ~.8 every 2-3 days requiring ~1 gallon of MA each week, the rest of my readings are fine. TA is 70, CYA is 60 (waiting to raise more due to CH levels).
So question for any experts, is the CH raising because of the new plaster, and is that normal? Are there any problems that can arise due to high CH levels? The blue color plaster isn't uniform in color (some areas darker than others), and this week we've started getting very dark spots that almost look like deposits on the plaster. I wasn't sure if that could be caused by high CH or not. If i want to get the levels back down to normal, I'd have to drain 1/3-1/2 of the water, which seems excessive, especially since it's mid-summer and it wouldn't be usable while i drain/refill.
So any suggestions? will it be fine for the season, at which point I'd be draining it for closing anyways? If the high CH levels aren't causing the discoloring areas, any ideas what it could be?
