Calcium Hardness 100
I put Phosfree into pull three times now (i started with reading of about 800 phosphates). I have cleaned filter before and after and now am putting maintenance **** in it every week. Doesn't seem to help. I can't get rid of it. I'm ready to move and forget this freaking pool . Help!!
The pool math says remove 20% of pool water (earlier this year I removed 70 %). Also calcultor says add 355 oz of calcium chloride (really?). Will this make a difference in my algae??
