Saw this on YouTube, how well would this work? At all? Anyone tried before?

All of the bed filters I've seen have much deeper sand and water circulation in a tower of some sort, not as substrate. I like the idea for keep junk off the tank bottom but have to wonder if it would be nearly as effective for BB.
 
It's just a reverse flow UGF not a fluidized bed as indicated. Fluidized bed requires flow through suspended media (mostly sand).

Under the sand would become a collection of muck. Not something you want in your tank.

That is kind of what I was thinking as far as being useful. Good point on the collection of junk under the sand. Hadn't thought of that.
 
LOL that was mine. I pulled it out of the tank after 3 days because the pvc tubing that I used kept floating to the top of the sand.

Here is a pic of the pvc

If it makes you feel any better I was looking on YouTube after watching the video you put up of the awesome acrylic one in your sump!

Here is a link to another site's article about this subject. I am planning to try this idea when I get time. I think this project as they lay it out will both keep the junk off the bottom and avoid the muck issue that others have talked about.
