Otherwise you will spend time everyday or so going to that tube and sucking on it to get the airbubbles out.

Sucking the air out is not fun. Saltwater tastes BAD!

You are more than welcome to come check out my setup. It may give you some ideas about the way it works. It always help sme understand the way things work if I see them in action.
