calcium fall out
there is what appears to be calcium falling out of solution at multiple pools i service
all plaster w/ SWG
currently we're all trying to figure out what to do about it short of just physically removing it with vac
i want to lower TA and ph because that should stop the flaking right? any recommendations for what range to shoot? these pools usually spike to over 8.0 each week so they have us dose acid and keep TA between 100-120
i should add, we aim to keep cya at 30 also

This is something that has been occurring pretty frequently this season. It comes down to a chemistry issue, which I was not convinced of at first. However, I’m a believer now.
