Well I have been doing a lot of vacuuming and getting some settling in a lot of areas and I thought I was getting algae again. The water was not as clear as before. I tested last night and had FC 6.5 at 40 CYA and this morning I checked it was 6ppm. So I guess I don't have a algae problem. We have a new house going in next door and have several huge dirt piles next to house. I'm hoping this is only dirt settling in the pool and making it cloudy. I tried to swim down and investigate and it just disappears into the water when you brush it.
