The water near the steps.. about 3.5 feet is clear but the deep end of it.. 11ft portion still remains cloudy. I put an algaecide and that cleared off after a few days and I vac out the 'white' stuff that remains below.I also put in DE which helps to capture the microscopic particles.. from 8-11 ft the water remains cloudy. What can I do. I had filled water back to remove impurities before and that worked out well but now it is not...By the way pool chemically is all balanced with the SWG.
