[joe-ejs]

Hello.

I am starting up a Phyto colony and am trying to locate the Rigid tubing that will connect to the standard airline tubing. I need rigid tubing with an outside diameter of 3/16". I can't seem to find it on Amazon..BRS does not have it. Am I looking for teh wring size? Has anyone else been able to find it?
