Hey Fog - if youy haven't already check out my post in this thread for some help with owning a DE filter.

If you've got to clear a swamp, you might try putting a Hayward SP 1091-Z-7 (backwash adapter) in the drain hole and connect a hose to it so you can ~ 'vacuum to waste'. This would bypass most of the filter fingers and might be easier than all the bumping and dumping you are currently doing (* however, it's gonna cost you a lot of gallons of water).

Keep us informed as to your progress, we're rooting for you!
