I didn't cover my pool last year (big mistake I won't make again) so I ended up with a mess when I opened on 5/22. I've been SLAMing since and I think I'm juuuust about in the clear. Yesterday, I noticed there's is a film on the vertical walls of my liner. It's no where to be seen on the slants to the deep end or the bottom. It's a bit rough to the touch. If I run my nails on it to scrape some off, it is a bit yellow in color and gritty. It does not come off easily with my brush.
Any idea what this could be? My pool had a nice carpet of algae on nearly the whole thing.
I SLAMed with Great Value Unscented bleach from WalMart, Pool Shock and a few hits of granular Chlorine.
FC - 16 (Recommended SLAM level)
pH - 7.6
TA - 70
CH - 90
CYA - 85
