New to this forum and hope someone can help.
Pool is roughly 10m x 5m. 2m deep at the deep end and concrete painted.
We didn't manage to get the leaves out before we closed it last year and, of course, when I opened it this year it was green pea soup. After about 3 weeks the water finally cleared, but we were left with black algae on the bottom and it's spreading!
I don't want to have to empty the pool (water is metered).
I'm thinking bleach bleach bleach and lots of Chlor choc. Am I going in the right direction?
