Carl, the trick with DE in a sand filter has been around for a long time. I first heard about it about 20 years ago from my neighbor with a pool (I didn't own a pool back then). He learned it from his pool service guy!
It's funny how whenever someone posts information about a product that is somewhat out of the norm the naysayers come out in great numbers. I'm speaking from actual experience in using the product.

Do the research & look at the test results. I think you will find that indeed Zeolite does provide equal to or better filtration properties than DE. It's less maint and is easier on the envionrment.

I have large aquariums but your talking about two completely different environments with different pump and filter equipment exposed to different elements under different conditions. Lets compare apples to apples.

All I can tell you is I've had no iron staining, algea or any other water treatment issues. I love my almost maint free pool.
