Dosing line

[anthonyt987]

When dosing do you guys use ro line or air line tubing?

I saw in a video that ro line was better, more accurate, doesnt expand etc

but my ro line has cracked like 5x where it connects on the nipple, I even super glued it to make sure it was sealed. I went based off this video

I have always used RO line without any issues.

I use RO line too, and have had cracking of the line at the nipple in the past. What I do is simply heat up the end of the RO line a bit with a lighter so it's pliable, then push it onto the nipple. Stops it from cracking.
