Hello all, Just curious if there is a way I can use DE powder from the pool store in conjuction with my 404 for water polishing? Is it possible to put it in a media bad and put it in a tray? or do I have the wrong idea...any thoughts would be cool.

You can do that if you have a Diatom filter. Most media bags will allow the DE to flow right through them. I doubt there is any cheap way to make a 404 into a diatom filter.

I would not recommend it... DE is a fine powder, and it will not stay in that bag. You need a no-bypass filter like a magnum with a microfilter cartridge, or a dedicated diatom filter, like a Vortex.
