Everything was great except my calcium hardness. I added enough to raise ch from 100 to 200, and the free chlorine went from 3 ppm to zero in 1 hour.
Is that common that calcium chloride depletes chlorine?
I since added chlorine but was curious if anyone knew of whether adding the cal. chloride knocks down the fc levels?
