Hello guys. I have a problem with my pool, Pool water is clear but the walls, steps, and floor looks like rust. I think it is algae. It will not rub off. I put in Yellow Out, shock, algaecide 60, 6 gallons of bleach and nothing seems to work. Also cleaned the filter.
Now I am lost all of this was over 2 week period. Any suggestions? Thank you for any info.
