Thanks Windsong,

But the reason I thought of using ZEOLITE is because of its immediate
(???????) action in absorbing amonia. I don't know if the fish would
survive 6-8 wks for the filter to get going.

3. Can I put ZEOLITE as bottom gravel in my 160 gal. pond?

## It's a temporary fix and a waste of money. Use Real gravel.
