That explains why a working solution of PC-TEA or the like, made with my hard well water and left standing in an open pitcher, will turn cloudy as would a developer like Dektol. I'm assuming that the TEA makes a carbonate out of CO2 from air which it hands over to the Mg and Ca in the well water making limestone as the cloudy stuff. OTH, even a glass of well water standing open should become cloudy. Anyway, it's very good drinking water from 110 feet down. If I ever get a water softener, I shall put a tap between the well and the softener for drink.
