I think I have calcium clouding. I added too much soda ash ( 4 cups when the pH was 7.2 ) and immediately got clouding. I had calcium levels of 350 a while back. After adding the soda ash the pH was 8.0 and TA around 115, cya around 70 and FC about 3, and the CH is at 225. I've run the filter for 12 hrs. and it's significantly less cloudy (I have a sand filter). I also added 16 oz of ultra bright clarifier. Pool guy says it should clear within a few days and that I don't need to lower the pH. I have a 20,000 gal vinyl liner pool with a filter that doesn't appear to catch tiny particles. Should I do something else? What is the solution for calcium clouding? Thanks a lot! Glenn (new member)
