Coral Life Skimmer Not making bubbles

[swivel]

i just put my skimmer in the sump and for some reason it is not making bubbles in the skimmer like it should.

do you have your air line hooked to your pump or basicly check for any type of restrictions in the air line.

Also make sure that the pump is not submerged too deep. They will pull more air if the pump it closer to the surface of the water.

Over time the venturi will buildup some salt on the airline side, I usually use a small drill bit to clean it out by hand, not with a drill.
