I have a 35+ year old swimming pool with an American Titan Vertical Grid (screen) filter that uses diatomacous earth as a filter media. The screens are expensive and when I backwash it, and pour in new D.E. I get tons of D.E. in the pool. I've inspected the screens and it seems even with little tiny holes it still blows D. E. into the pool. New 7+1 half screens are about $250 on Amazon.

I've got to think that newer technology is available. Cartridges that you can backwash? I'll goggle search, but any thoughts. At this point, I don't mind spending a few hundred $ to quit having to deal with this.
