I'm new to taking care of a pool. The algae has taken over, it's very green. The pH on the Pool Style test kit is showing between 7.8 - 8.2; the BR/CL level is 6.5 & 3.0. I've added shock and algaecide, per my local pool store's suggestions. Also brushing and vacuuming daily. Suggestions please? I'm just so frustrated.
