Can't seem to find info on this. It's certainly not in the silly instructions that came with my Jebao doser. I'm only using two of the four channels so have the two extra tubes as replacements but have no idea how long they should be expected to last.
Are there any generally accepted guidelines or anyone have experience to base some on? I would rather not run to failure.
