I recently bought a home with an in ground gunite pool. I had a pool company open the pool in first week in June and the water has been cloudy ever since. I have shocked / slammed several times with the most recent being 7/14 through 7/17. My current levels are: CH-425, TA-90, CYA-40, FC-5 (loss is less than 1 over night), CC-0, PH-7.4. I have run my filter 24/7 during the month of June ($185 electric bill with no one living in the house) I have vacuumed to waist several times, recently added DE to my sand filter and ran it for days non stop. I have added clarifier on several occasions at the advice of my friendly pool store salesmen. I recently opened the filter to redistribute the sand and even added Sparkle Up to aid in filtration. And to this day, I can see millions of white suspended particles floating in my pool when the sun hits the water just right or at night with the light on. I really don't know where to go from here.
