I was think about putting this down on my egg crate for a couple reasons; one being little particles wont fall through like screen and two it creates another area for micro organisms. Its the type of foam used in fish filter, would like some thoughts on this please

I think it sounds like an awesome idea I think I'll steal it myself actually

Thanks, I guess a fish background can help a lil in the frog world

I used filter foam myself. It is perfect for this! I would put this instead of egg crate.
I use a pump to get the water across the filter foam (as a filter).

have to consider what you're putting on it as far as weight goes. If it's a thin layer, that's one thing, but if it's a thick pad of it, you'll see it pushed down by anything (wood, primarily) heavy.

I thought you used it to access the pump...

That sounds like a great idea to me, especially using it as an access to the pump. I might try that on my next build. (this weekend)

The bottom (except the water feature) consist of filter foam with epiweb on top of it. The water flows from the waterfall (right) through the filter foam back to the pump on the left side. So the filter foam is also my filter.

will it be one big piece? where are you buying it? dimensions?

Should be able to get it at your local hardware store, its sold for making filters for air conditioners. I learned this trick for fish filter media a while back
