Where to buy CO2 Proof Tubing?

[snickle]

I am planning on putting my CO2 Cylinder in the basement and running a line up to the tank. Where can I get CO2 proof tubing reasonably priced?

Petsmart sells silicone tubing. It's just a little more expensive than regular.

Silicon Tubing is not the greatest for CO2. Here's a chart explaining the permeabilities of various materials for various gasses:

Also, I think a lot of the sellers of CO2 tubing get it from this source:

Clippard is great and Aquaticeco.com under Tygon tubing is some of the best also.

Cheap and nice.

Polyethylene tubing at Lowe's is good and dirt cheap. The catch is its just available in foggy clear color and its stiff. Think its like 8 cents a foot. If you cant see it then it works great. If its going in the tank you can switch to a more expensive better looking tubbing once it hits the water.

So what would happen if I was to use regular aquarium airline tubing? Does it create some kind of chemical reaction that's harmful for the fish, or will it just wear out more quickly and need to be replaced?

Not so much a wear issue, as normal airline tubing is permeable to CO2, so you would be losing CO2 to the air. A waste.
