I'm building my first home-made yeast CO2 injector, and have a couple of 
questions that I'd appreciate your advice on:

1) Does the bottle have to be above the aquarium?

2) Would a check valve help if it were to be paced below the aquarium?

3) Should the bottle be placed upright or on its side?

4) I'm planning to vent the CO2 into the intake of a Fluval 403 canister
filter. What is the best way to do this? E.g., stuff the airline tubing
directly into the side of the intake, add a disposable air stone and let the
CO2 bubble up into the intake from below?
