I have a Gunite Pool. 28,000 Gallons. 20'x40'
A little over a month ago I tested for CH & it was Low at 180. So I added 33 LBs of Calcium Chloride & that brought it up to 300. Now a little over a month later I tested again & it's back down to 180.
I know how important Calcium is to a Plaster Pool. I have 2 small spots the size of a nickel where it looks like Plaster might have been eaten away.
Yes, there has been rain here. But I don't think enough to lower that much. Why is my Pool constantly needing & eating up Calcium Chloride?
CH: 180 ???
Thanks in advance!
