minijet 606 blowing air bubbles

[slowhand383]

In the back chamber of my JBJ nano, my minijet 606 is blowing out tiny little air bubbles about every 5 to 10 seconds. I cant figure it out. If the pump and outlet nozzle are fully submerged then where is the air coming from? Thank you for any help.

yeah i have been having the same problem with the exact same setup. i was thinking it was from the tubing not fully sealed at the top part and sucking in air once in a while, so i tried to tighten the zip tie to prevent it. seems to work better now. good luck.
