I have used the green to blue product out by hth. I thought it would be okay since I have a regular sand filter. The problem is that when I am vacuuming up the material in the bottom, the filter is sending the nasty water back into my pool. Everything I vacuum up is floating again. I have backwashed over and over again. It doesn't help but for a minute or two and then it starts again. What do I do?
Can I vacuum pool on a backwash setting? I currently vacuum on filter setting. PLEASE HELP. I have friends coming over in 2 hours and prefer my water to not be disgusting.
