I've completed my slamming and I've added plenty of floc to my pool. The dead algae looks to be coming together. But it's all floating on top of my water. The water underneath is blue. I generally use floc at night but I came to this stage this morning. So now I'm wondering if this is the usual process it goes through before it sinks Or if I have another problem going on. And is there anyway to help these huge clumps of dead algae fall besides adding more floc.
