I don't understand how the canister diffusion technique is LESS efficient
than a diffusor... If you really think about it, it is actually MORE
efficient and probably the same as a reactor (at least in my setup).. I
bubble my CO2 (pressurized, regulator, needle valve, bubble counter, then
into the intake of my Eheim) and I RARELY get a belch from my spray bar
(submerged).
What does this mean? Almost ALL the CO2 put into the Eheim ends up in the
water, which equates to close to 100% efficiency, MUCH better than a
diffusor in which a significant percentage of bubbles make it to the surface
undissolved...
