Black Heart, I could help, remotely with DIY Co2 if you'd like, best advice you'll get, don't use PVC hosing, or silicone, use silicone tubing and gorilla glue, then cover that with silicone for an extra bit of security. Had 2 breaches in my bottles already that I think I've resealed. My next attempt at this will involve more bottles, with less pressure per bottle, and a whole lot more check valves.
Duckmasta, have you checked out Menards? they have a large selection of Full tube Fluorescent set up, I think they have 8" through 12 foot bulbs on hand at the Clio one.
Best of luck though.
Oh and I have an interview for an actual career tomorrow, wish me luck.
