I have been having some stubborn algae spots this season. I brush the pool regularly and especially in those areas. I shock the pool regularly, started to use Algaecide, have ideal numbers for the pool and still get green algae a day or two after shocking the pool. It’s mostly patches in certain areas. Using trichlor pucks this season.
