Have started managing my own pool for past two months. Thanks to all on this forum for the great advice. All my pool chemistry numbers are on target except for one, Calcium Hardness. I have a plaster pool and have been measuring a Calcium Hardness of 100 ppm when the suggested range is 250 to 350. When I test for Total Hardness (using test strips) I measure around 300ppm. Do I need to take any action to increase the Calcium level in my pool given the Total Hardness value?
Any help is appreciated.
