I have a small above ground Vinyl pool about 4700 gal. We had a bunch of rain and the water started to get greenish so I shocked it crazy. Now there is the dead algae in milky clouds if I use my vacuum it just stirs it up and the whole pool is cloudy. If I run the pound it gets cloudy, I put Flocctant in it I think that’s what it is called, to turn it solid so I could vacuum it nope didn’t work someone please help!
