Hose barb size for Eheim 2215

I'm preparing to build a DIY CO2 reactor in anticipation of my Eheim 2215 canister filter slated to arrive tomorrow. I've done some research on the tubing size of the filter, but I'm getting mixed results. I need to buy nylon hose barbs for my reactor, but I'm unsure of the size they need to be. Should I be buying 1/2" ID or 5/8" ID barbs?

My 2217 has 2 sizes, the input inner diameter is 5/8 (16mm), output inner diameter is 1/2 (12mm).

Not sure but I think it's the same for 2215. Check your tubing.
