Thanks guys. I am convinced that the pump is too large for the filter. I researched the pump on line , it is rated @ 160 gpm my filter is rated at 75gpm. My pool dealers response to this fact was "well we sold 100's of these without any problems". A rep is coming to look at it on Saturday(i hope). Although the filter is out matched it is catching most of the debris. What the filter can't catch looks like a fine "dirt/dust" that settles at the bottom of the pool in clumps here and there. I am thinking about trying to vac it again,accept this time I will have the filter discharge the sucked up water as apposed to recycle it. I am sure glad I put plenty of shut off valves
