So pool has been opened for 6 weeks and has been beautiful and clear as well. We had some people over to swim over the weekend and I turned up the SWG just in case. I checked the FC yesterday and it was 3.0, so I topped it off with a bottle of bleach and set the SWG up to 60%. Today I checked the water and the FC was 1.5 and it looked cloudy. The PH has been around 7.3 and today it was 7.1. The weather has been cooler and the solar cover has been on the pool and lots of dirt and pollen got into the water when I rolled it up on the weekend. So what is causing the cloudy water? Am I making the right call to shock it? (Can't hurt, but it does cost money).
PH 7.1 (raising to 7.6)
FC 1.5 (bringing to shock level)
