Yeah, I've heard of those. I think if you just google "Reverse Carlson" you ought to find something. They are a neat idea but I think drawback is that, at least as I understand it, you have to have this chamber inside your tank which to me means it's likely not suitable for a small tank. Even for a regular size tank you'd want this thing hidden off to the side or the back in some unviewable area kind of thing..
