Elite Mini Filter - A-130

Is the filter supposed to have air bubbles in the tank to show the filter is working?

The bubbles (air) should be on as long as you have pressed the + sign on the adjustable flow control. If you see any condensation or water inside the air line tube, remove the air line tube and blow in it to remove any water and then re-attach it. If water/condensation is inside the tube the airline has no way of getting any air to go through. Then press the (-) sign and then back to the (+) sign the bubbles should start back up again. It is not necessary for the bubbles to be on all the time, as long as you see water movement the filter is providing enough air for your fish. We hope that this helps.
