Greetings Experts! I’ve recently used Algaecide to turn my pool from green to clean. I was able to vacuum and filter out all the dead algae. But now I have stubborn algae residue that is sticking to my plaster pool surface and will not come off. I’ve tried hard brushing, vacuuming, chlorine, Algaecide, etc. you name it and nothing works! The sticky slippery stain just reappears after a few hours.
Any tips??
