My pollen glass diffuser created major amounts of condensation inside my aquarium hood (wasting CO2 gas). My brother, visiting from Europe, gave me this Dennerle CO2 diffuser. It is absolutely awesome! Not only is there zero condensation, you can literally watch the CO2 dissolve into the water: you can see the bubbles shrink in size to almost zero by the time they hit the flipper at the top. Besides, it is cool to watch them zig-zag the ramps and it has a built in bubble counter: count the bubbles as they come out of the dispenser. Best gift ever I received for my aquarium.
