Hmm... I suppose you can use any type of plastic container that is bottle shaped and able to hold some pressure. Generally soda bottles are the cheapest option to go with. As for rigid CO2 tubing yes, you can find it on this page http://www.marinedepot.com/ps_ViewIt...ategory=FICOTU

I'm also not sure about using lime wood. If it has lime in it the CO2 will quickly dissolve it since CO2 + water = carbonic acid. Try using a piece of a bamboo chopstick. It won't dissolve, is cheap, and makes a great diffuser.
