CO2 tubing for Reactor?

[Mark]

I was wondering how many of you are using CO2-stable airline tubing over regular airline tubing in your calcium reactor set ups. I read that up to 20 percent of the CO2 is lost through regular silicone tubing. I figure the CO2 stable tubing I see at mailorder sites would make the CO2 supply last longer. I'm collecting all the pieces to set up my future reactor, and didn't whether to get this stuff.
