A few checks to carry out if you are getting any bubbles when using your venturi.

  • Check the the clear airline has no kinks or damage
  • Check to make sure the airline is fully connected to the filter, check your user manual to where this connects.
  • Make sure the black valve is located outside the water of the aquarium tank
  • Check the black valve is fully open, to do this twist the top of the black valve, you can open and close this to add or reduce the oxygen this will pull through
