I had been using the test strips checking algae the past week and the FC tested within range. Then, Saturday morning, I noticed that the pool looked a bit cloudy. I used my TF-100 kit and found the FC at 2.0 and the cc at 0. I then added the required chlorine 2 days ago. Then, yesterday, I freaked out about it and added another gallon of chlorine yesterday. I have cleaned the filter each day and have an automatic pool cleaner running and the pool pump on 24x7. This morning, it is still cloudy. I tested the FC and it is at 12. I am leaving for 7 days starting tomorrow and my pool is still a bit cloudy. Any suggestions?
