Skimmer not working

[dustinreef]

My protein skimmer has stoped collecting waste in the cup. And the swirl does not skim. The water comes in the skimmer and out the top. If anyone knows how to fix this kind of problem please reply.

[rytrearc]

Are air bubbles produced in the skimmer body like normal?

Did the air tube detach from the pump?

what is your water level at

It sounds like the air hose isn't present or is in the water.
