Have anybody try out the new Hagen CO2 unit yet??

They guarantee lush plant growth. That's a pretty bold statement.

The Hagan system is a yeast system (based upon what I have read). IT also used the 'slow rising bubble' mthod of gas diffusion, which I have never had much luck with.

My concern is that they are claiming a month of gas from a very small amount of solution compared to what most of us use in our bottles.
