    Has anyone thought about using a penductor in a reactor to enhance CO2 dissolution? Penductors use the venturi principle to enhance water flow produced by a pump, often by up to a factor of 5! So here's my general idea. Get a reactor tube, probably 2" or 3" PVC, pipe flow into the tube through a penductor. Inject CO2 at the 1/2 to 2/3 point down the tube with outflow at the other end. The enhanced flow would be diminished by the pipe dimensions, but if for every gallon in (and out) you moved, say, three gallons the length of the tube, that ought to produce a lot of mixing. Now, if you had the internal outlet of the CO2 be a limewood block or the like, the small bubbles ought to be thoroughly mixed. If they do accumulate at the top, the venturi action of the penductor ought to rip them up and mix them around.

    I'd try this, but I've got a nice set up now with a Barr-like venturi reactor--the DIY reactor has an outlet to a mazzei injector near the tank outflow. The water isn't recirculated through the reactor like Tom's, but, rather, "venturied" into the tank, producing bubbles on top of water with good CO2 dissolution.

    Adding the loop back to the tank, post reactor etc, is not a bad method, but means more mist inside the tank.
