Free Clorine

Welcome to the forum, Walk

We will need a lot more information before we can be of specific help.

Mostly how much water is in the pool and the other test results, particularly CYA level.

The conventional wisdom you will find here, will be to use Ben's Best Guess Chart and take your Free Chlorine above shock level and keep it there until the Algae is GONE Then keep it there for another day or two. This will mean testing several times a day and adding bleach to maintain the level above the shock level. Along with that ---- Brush, Vacuum, Brush, Brush, Vacuum, Brush, Brush, Vacuum, Brush,--- lots of patience is required but if you follow the advise here, you will have clear water in no time.
