Home Brew Co2

I would set up a reservoir between the two systems, something like a 2 litre coke bottle, and have non return valves either side of it, as beer can "blow off" as the home brewers calls it, as well as the risk of the aquarium syphoning backwards. Good luck with that. Other than that, keep all your equipment seperate!

What I'm saying is I don't think you can have non-return valves pointing in both directions, or nothing will move through it, but both the alcohol and the aquarium have the potential to either syphon back or gas off, so that's why I recommended a reservoir.
