So I won't go into it, but I am still fighting some filter issues from my original the meantime I figured I would try a 1 micron "slime bag" over the returns to see just how much dirt is actually being missed by the filter.

Well, guess what...the bag is catching some of the dirt, but a whole lot is just "blowing" right through the 1 micron bag. How is this possible ?

See this thread for a bit more info on the bag...!/page2
