Hi this is my first winter with the pool and now that the water is 65. my Calcite Saturation Index is going neg 3.1 now.
here are My numbers
Pool is plaster just a year old now. just do not want Plaster to get messed up.
so would letting PH go up to 7.8 be ok. or should I just add some calcium chloride to get CH to 350 to 400 range for the winter Thanks for any help have kept pool water bal all summer just now with cool water is messing me up some.
