Oh yeah, by whole system, Ithink Kathy means you don't need
the whole Hagen system. NOt that the hagen diffuser is
asubstiture for all the other CO2 stuff. The whole Hagen
system is just a yeast fermentation set up, minus the
bottle, right? But the bubble rector is neat.
Like the Aqua-Medic/AB unit included inthe AZ Gardens
system but much cheaper ;-)

the one that you
can watch the bubbles get smaller at the CO2 diffuse,
great for a
chemistry lesson and cool to watch. don't buy the whole
system, just the
diffuser that clips inside the tank.
