Has anyone had trouble with CO2 corroding a canister filter (specifically an Eheim)? I ask because right now I'm injecting CO2 directing into the canister and it doesn't airlock (which is good). However, I don't want to continue this if it's going to cause corrosion in the filter. Thanks.

CO2 will not corrode an Eheim - it is all polymers. If you have a heating element in the Eheim it is metallic, but should still be fine - if uneasy about that, opt for the SW version of the heater.
