For the past year I've been using a homemade CO2 generator. I've
experimented with several ways to diffuse the CO2 in the water
andfinally I just a T-valve and hooked my generator into my air lines.

After I make the water sugar yeast mix, I hook it up (no need to wait)
and the oxygen pressurizes my bottle (since it can easily escape through
the air stone the pressure cannot build up greatly, it can only equalize).

Once the yeast starts working a mix of Oxy (for fish and asthetics) and
CO2 (for plants) is released into the tank.

Any opinions or thoughts about this method?
