I have crystal clear pool water, so I can see all of the stuff accumulated on the bottom. It is fine powdery stuff that I cant pick up with my hands. I took out my filter and cleaned it very well then I vacuumed. The stuff I am taking off the pool bottom is shooting straight back into the pool. Now my water is milky. Should I have someone unscrew the drain plug in my filter casing while I vacuum as fast as I can and let the water go into the yard???? I am at my wits end.
