Only the 2nd time we've opened above ground pool and after initial shock and algaecide pool was greenish yellow and cloudy. Shocked it a 2nd time two days later and got no change. Levels for everything were fine, and pool store recommended using flocculant to clear it up. Put it in and recirculated for 2 hours before shutting off for the night. not much change this moring, but the afternoon everything was clumping on the surface. It didn't help that we had thunderstorms and hi wind and a bunch of Crud blew in as well. Any ideas on how to get the floc off the surface? Will it sink if I just wait?
