I use the same thing. Hagen airline tubing.

I use vinyl air tubing from the hardware store. The walls are much thicker than aquarium tubing.

Do you mean silicone, or is silly-cone a brand name? Silicone is safe to use, but it tends to leak a lot. I still use it though... doesn't make THAT much of a difference. But if you are an efficiency stickler, use something else. There's a post somewhere about the different permiabilities of different materials. Do a search for "silicone" and "co2" and you should be able to find it.

EEEkk,..

I am having some CO2 delivery problem to my reactor and am trying to hunt down a pressure loss, guess I'll be ditching that silicone tubing also..

VYNIL is FINAL..

I found a regulator but I can't figure out it's pressure rating, even on the internet, the company seems to have gone out of business..

LOL see, vinyl is not permeable to co2, but doesn't it get affected by all the co2, with the acidity and the reacting and the breaking down..oiy!
