I had a large bool now gone. Left black stains on steps and bottom of my inground pool.
I tried ascorbic acid but bot work well- probably had too much chlorine in water and insufficient ascorbic acid. Loks like ascorbic acid is for metals anyway.
Can anyone help with advice on what to use- short of empty and acid wash- to fremove algae stains?
Thanks
Mark
