Plumbing two tanks together
So I have an extra ten gallon tank I was going to set up right next to a 20 gallon I have going. A 206 canister and CO2 system will be right there in between. I think I've seen you can add an extra manifold to get CO2 to the second tank, but has anyone plumbed in to use one canister for two tanks? I feel like preventing overflows may be tricky.
