The tank they were in is a pretty hevily planted tank, and I am injecting CO2. Is there an effiecient way to add CO2 to the tank without any power source to break up the bubbles. I should probably post this question on the APD. Thanks ===== J. Miller Edmonton, AB, Can. __________________________________________________ Do You Yahoo!? Get email at your own domain with Yahoo!
