Re: How do you know when to replaster your pool
That's tough to say. Have you tried elevating your chlorine to shock levels until you pass the overnight test? If you get into the pool with a hand brush, that may help too.
If you can do the above and get rid of the algae, then it is mostly a cosmetic issue.
