regular polypropylene or special CO2 tubing?

[salty joe]

I'm almost done with my calcium reactor and need to buy tubing.
According to this chart, polypropylene has excellent resistance to CO2. Is there any reason to buy the stuff advertised as specifically for CO2 instead of regular old polypropylene tubing?

Regular PP is fine.

I prefer medical grade Tygon tubing personally, its much softer and easier to work with, you just have to use the plastic tube clamps on the ends.
