does anyone do it?

Does Ozone count? :D
I do use a filter sock as well for the bigger junk
But my water is like crystal :)

i was thinking more along the powdered fossil medium

[CastleRock]

I used to use that diatom powder stuff on my Discus tanks, made a mess half the time turned the tank white with the powder but the big canister filter it was in cleaned it right back up and did a great job on polishing the water
But never used it in any of my salt set ups

Does it remove the small food particles the corals like?

[murfman]

it filters down to like 1 micron

What is sacrificed as a result?

[murfman]

i would think that running this full time would take away the phytoplankton and benificial creatures in the water column. i know most fw tanks they run it just to clear up the water. i was wondering if any sw reef keepers use it. I know i cleaned the filters in my sea horse tank and added some carbon and the water is very clear now.

That's what I suspect would happen. Carbon seems to work fine for me, and I imagine it removes a number of contaminants and improves water quality in ways that polishing can't.
