Dosing Container air bubbles…

[ASIN28]

Hey I can use some help. So I am setting up my reefdose2 and made it so I am dosing directly out of the ESV 1 gallon containers. I am using the bulkhead shark bite fittings from BRS. Why am I getting air bubbles through the line I primed it and everything and probably took out 20ml already and I still seem to still be getting air bubbles.

*I am have 2 different tubing set up just to see which I prefer, the black is actual airline tubing and the clear is from home depot*
I also saw the reviews on these bullhead fittings from BRS that they don’t hold a seal but they seem to be holding a seal for me

At this point it seems like it is a process of elimination. See what you can replace or bypass. It appears that air is leaking in to one of your connections or the end isn't full submerged. Good luck with your search!
