The pool was green when we took the cover off, and we have added about 50 pounds of shock over the last two weeks. The water is now cloudy....no green but we can not get the water balanced. Pool will not hold chlorine. Water results showed 0 TC, 0 FC, 6.4 PH, 30 ALK, 100 CH, 0 Stablizer. I added 6 lbs of shock, 25lbs of Alkalinity and 11 lbs of stabilizer. The next day, I had 0 TC, 0 FC, 6.4 PH, 30 ALK, 150 CH, 0 Stablizer. Any ideas?
