OK I just took a look at the link iaefebs posted up, maybe this will work. He is using a peristaltic pump which would definitely help with the turbulence issue. Consider me subscribed.
Yeah there's definitely a good chance this wont work due to foaming. I'm going to try and pwm the pump to slow it down as much as I can and forego the ball valve which should help some. Keeping my fingers crossed this actually works =]
