    Worked a Treat

    I got this chemical to treat my pool that had just started to show black algae spots. I brushed the pool with a wire pool brush and then treated the water by dissolving the powder in a large bucket and then pouring the water into the pool. The pool pump ran all day and I brushed the spots again to remove them.

    I had to treat the pool twice to get rid of the spots as I found the first treatment didn't seem to touch them. After the second treatment when I brushed the spots I could see them fall away from the pool walls. You do have to work at brushing the spots to remove them as it is very stubborn and likes to stay stuck to the walls.

    I contacted customer service after the first treatment didn't work and they were really helpful with what to do and how to treat them. It was above what I was expecting so thank you for all your help.

    If you have black algae I would buy two lots of the chemical as one may not be enough.
