I am a new pool owner and I have a problem. I have something whiteish in color, kinda looks like cotton balls pulled apart that settles out in the bottom. When I vaccum or brush it they go away but then settle back out after a while. I use the Pool Frog system right now (but I am getting rid of it) and the other day when I did the algaecide it went away but the next day when I shocked it came back. It starting formimg before I ever put any algaecide in the pool also. Please help as I cannot find anything on this site or the net that sounds like this. Thanks !!!
