When we opened 3 weeks ago, the water was crystal clear. After the winter and being closed for 6 months, I somehow didn't have a swamp. Opening was effortless. Now the water is very, very cloudy. There is no color to it, just cloudy. Since we have a Nature 2, I have been keeping the FC right around .8 to 1.0. On Saturday evening, I noticed it was getting a little cloudy and threw in a gallon of 6% clorox, which brought FC to 1.4. It was rainy and cold all day and the pool got cloudier and cloudier. Since I have read that cloudy water warrants a shock treatment, I did so last evening and now the water is even cloudier. Is the higher chlorine combined with the Nature 2 causing the cloudy water? What should I do?
