Brohawk's solution is pretty cool - I'd never thought of blowing it in via the cylinder. I have reactors, with the check valves below the bc's (simple HK glass jobbies). During lights off, water from the reactor creeps back down into the bc (which isn't far below the reactor input), so I never have to worry about the cv emptying.
Anyway, assuming your tubing isn't horribly difficult to pull off a metal barb (and it will get easier the more you remove it), this sounds like a pretty good solution. And if you ever feel like the tubing is sliding off too easily, cut an inch off and start again.
