Well I just got the house and Jason helped me get everything cleaned up and running well using the BBB method. We have been swimming about every other day and when I take the solar cover off the pool is crystal clear but the bottom is spotted with yellow spots.
It isn't sand, or dirt and you kind of have to brush it to get it to come off the bottom. If you just swirl the water around it, it won't move. When you do brush it, it kind of clouds then vanishes.
The spots are mostly the size of a dime but some are the size of a fifty cent piece. I would say there are 30 spots or so every other day.
Is this possible mustard algae, I was reading that it was pretty rare to get so I didn't want to jump to conclusions.
