So, I tried the DE thing this year. got a 2 pound drop in pressure (this is the first oddity), I find my pressure drops as the system becomes restricted any when from the skimmer to the input side of the sand.

4 hours later, all of the DE was in the skimmer sock which off course blew the prime.

So, I'm thinking my pump is pushing too hard for the filter? I run at 18lbs normal. The filter is a Hayward GM140 (takes 50# sand) and the pump I will post when I get home.
