I realize that there are many different paths that can be taken in order to get to the same destination, but I am having a very difficult time understanding why should I choose to take this one.
I currently use an Aqua Medic CO2 Reactor 1000, hanging externally on the back of the tank, with the return water from a Fluval 403 canister filter flowing through it (the return hose is actually set up with a "T", where one half goes through the reactor, and the other half goes to a Loc-Line flexible return, with each side having it's own ball valve so I can adjust the flow; currently, just about all of the return water is going to the reactor). The CO2 is very efficiently dissolved into the water, with no bubbles escaping out into the tank, where it seems to me they would just rise to the surface and pop, which would allow the CO2 to escape.
I have seen where other aquarists also use some type of reactor, but have also seen the various methods of blowing a CO2 mist out into the tank. It seems to me that the reactor method would be more efficient and a lot less likely to waste the CO2. Plus, I doubt any of the fish in nature would be presented with a cloud of CO2 in their water. Is there any real benefit from using this needle wheel pump method over a reactor?
