Test results from yesterday. Vinyl inground pool - 18 x 36 with 9' deep end (22,000 gallons?).

I added about 2 lbs of stabilizer yesterday and turned up the swg to raise the chlorine level.

Shooting for 2-3 on the FC reading right?

CC should be zero right? How do I drop that?

Pool has been open for about 3 weeks but I've spent very little time on it due to work. The water is actually clearing up nicely. I have another problem though with possibly mustard algae or something that collects on the seams and bottom of pool. When you brush it it disappears but then settles back down a couple hours later. My wife says it's dirt but I'm sure it's not because it will show up right after running the Aquabot and when you brush it it disappears into a cloud. You can't brush it around like you can with dirt. Anyone know what that is and how to get rid of it? It was a problem all of last year also.

Thanks in advance.
