Short version, asked someone to take care of my pool, they forgot, i came back and had algae. So thought I would try HTH Super Algae Guard as it said it killed and protected against algae. Unfortunately I think in my rush I mixed up the lower initial dose amount with a follow-up amount, so double dosed it, now my water is pretty murky/cloudy. Does that eventually wear off? Or do i have to drain the pool a bit?
