With this many tanks you will have lots (and lots and lots) of plumbing. I
suggest using semirigid copper tubing in place of vinyl/silicone for your
main run, and then branching off solenoid valves and/or needle valves for
each tank. Run the semirigid copper tubing along as a main run, and put
each solenoid/needle valve near the tank it will serve. The advantage to
doing this is that the copper tubing will not loose any CO2 or ever get
brittle like the vinyl/silicone stuff will do. You will also have a choice
of *lots* of brass fittings since the semirigid (also known as
refrigeration tubing) copper tubing is used commercially for all kinds of
things. For really cheap T's you can get commercially made copper T
fittings and solder them on.

Home Depot sells this in rolls of up to 50' (for 1/4") for <$50 or so. It's
cheaper than the CO2 resistant stuff, and I know it will hold up better.
