Okay so right now both of my bettas are in their own one gallon aquarium. The aquarium I have is this one.

If you can tell there is plastic tubing that goes down the middle that you slide the airline and airstone down into. Currently I've got the tube in the side of my tank. Without the plastic tube the bubbles are a little overwhelming for my bettas.
I'm getting a 10 gallon divided tank this weekend and plan to use one of the air pumps from my one gallon in my new tank. What I want to do though so the bubbles are still directed more towards the top of the tank is somehow connect the plastic tubes from both my 1 gallon aquariums together since the 10 gallon will be taller.
Does this make sense? And if so how can I go about connecting the tubes together?
