Interesting product....

Anybody had any experience or heard anything about these? Seems kind of cool and would save a lot of space for those with smaller sumps like myself.

I have used them very successfully (not this brand, I had something off of Amazon but exact same concept). Just put some chaeto in there and make sure to put the light on a timer so that it turns on when your display tank turns off. I was in pod heaven when I ran this on a 20 gallon.
