vortex reactor

["Kinney, Travis" <kinney at pdtarchs_com>]

How does the vortex reactor work (technically)? What causes the water to
swirl? Does the co2 enriched water exit through the foam? Is the bottom of
the reactor bell open or something? I was looking at the one for sale on
Aqua Botanic. I'm getting tired of the bubble noise going through my Fluval.
I was thinking that maybe adding one of those narrow airstones (the little
white ones that are about 2" long and 3/16" dia) at the end of my line so
that smaller bubbles get sucked up into canister. Maybe the smaller bubbles
will pass more freely through filter rather than gathering up near the
impeller. Any thoughts?
