Hello, sorry if this is slightly off topic, but didn't want to make a new thread for a simple question about suitable tubing for inline diffusers (I say simple, but I can't answer it, so maybe it's not).
What most people do is have the Co2 coming out of the cylinder through Polyurethane tubing which is connected to the diffuser in the tank.
I'm looking to have an inline diffuser to distribute the Co2 which will be added to the tubing that comes out of my filter and in to the tank. The tubing that I have is clear PVC.
From what I've read, PVC is not Co2 proof, but does this matter?
I can't find Polyurethane tubing at 20mm outer diameter, so I'm wondering how people use inline diffusers if Co2 proof tubing doesn't exist.
Thanks
