Algae spots on wall

[swmasson]

Hi everyone,

I have multiple green algae spots around the pool walls that I can’t seem to get rid off, I put some muratic acid in yesterday and then shocked the pool 4hrs later… Some has gone but these remaining spots won’t budge!

Any help appreciated!

Thanks

Steve

If you have visible algae, time to follow the SLAM Process
