Scale and stain removers (sodium hydroxide) purport to reduce calcium levels in the water. Where does the calcium go? (pool store said "it degrades", but fission doesn't happen with calcium). if it precipitates, what keeps it from scaling? Basically, how do scale and stain removers eliminate calcium without hurting the plaster?
