I liked how happy the kids were to pour fish poo-water into the potted plant
I'm of two minds on this one.
1) Anyone that tells you that you can get away without basic tank maintenance is absolutely full of the same stuff those kids were pouring out
2) The physics behind the design are sound, I'm guessing the substrate sits on a little stand so that there is a void underneath and when you add water to the tank to start the siphon all the waste is pulled into the void and up the tube.
Don't know how comfortable I'd be with no filter, and I didn't see anywhere for a heater either, also 1/2 gallon(with a tiny vertical footprint to boot) doesn't sound that great either.
