Rena XP2 tubing diameter (ID)

[helicopter]

I want to get some of those barbed hose fittings for plumbing my filter but I need to know what ID the tubing is. I think its 5/8 but I am not sure. Also I need to get some more tubing. I already ordered some but I ordered antibacterial tubing thinking it was a good idea but I read somewehre on here that all of those anti-... tubings are bad news in terms of being aquarium safe. I can get any other PVC tubing though right?

5/8" is correct.

I have no experience with the anti-bacterial tubing, but just about any other 5/8" tubing should work just fine.
