I've got a 10 gallon mid tech that I am hoping to inject CO2 into. I'm looking for a complete setup with diffuser (I'm not running a canister as there isn't any space at my desk for lines to go up to my aquarium. Alternately I can buy my own tank if you've got regulator, needle valve, solenoid, bubble counter, hosing, diffuser. I'm looking for something in excellent condition as the items will be somewhat visible.
Let me know if you've got anything.
