Hello,
I've attached 4 photos of what I assume to be a scum line on my pool. I'd appreciate any comments on how to clean it. A couple inches above that there is another line that appears to be a scale formation.
By the way, it has rained a few inches here in Phoenix over the last 24 hours (rare), so the pool level is now above these lines.
If I shock the pool now, would it possibly clean the currently submerged scum(?) line? Also I may add a quart of muratic acid.
If not, is there some other chemical I could add to remove them while the water level is so high?
Many Thanks,
Woodrow
