I'm as skeptical a person as you're going to find, especially about things like this. But I think we owe it to this bulletin board, and for the sake of rationality to deal with this device on its own terms.
It needs to be properly tested against the claims of its manufacturer, not ridiculed instead. The testing that could be done by Inland Reef Aquaria ought to serve as more than a simple analysis of this device. It could serve as an example of how to evaluate any device for aquarium use. We may think that this case is a "slam dunk" for evaluation of performance and think that testing is hardly even necessary. But instead it should serve as a good example of how to think intelligently about our aquariums and what is going on inside them. The function of many aquarium devices and methodologies are simply taken for granted.
I think it would surprise us all to learn than many of the things related to our aquariums are not what we think they are. This prospect has differing affects on hobbyists. For some it means a complete loss of direction, as if an explorer had their compass snatched from their hands. To others, it opens doorways to deeper understanding and gives pathways to success that were previously unimaginable.
Never forget that one of the most revolutionary devices of modern aquarium-keeping is a plastic sheet with holes in it - the undergravel filter. This monument to low-tech devices does exactly what it is designed to do with uncommon efficiency. It's sad that modern hobbyists who know nothing of undergravel filters, nor have ever used one, treat this device as some sort of comical "whipping-boy". They are incapable of intelligently thinking of it on its own terms, and so ignorance lives in a place where knowledge could reside.
