Protein Skimmer Issue

[Tank Lazy D]

Hi, all!

I have a small Protein skimmer on my 20 cube that is having some issues. It is a Reef Glass Nano tube with a rubber stopper on the top that has an inflow point and out flow point. The skimmer stopped producing bubbles so i cleaned out the tubbing, lots of stuff! Now it seams the pressure is to high in the tube. When I pull the top rubber stopper off just a it, it starts to bubble like crazy. When i put it on to just make a very light seal, it gets sucked down and no bubbling occurs. Any ideas?

Many protein skimmer issues stem from an inconsistent water level. Do you have an ATO?

I do have an ATO that keeps my water level pretty consistent.

I had to google this little skimmer to figure out how it was designed. Looking at pictures, I don't see how it's possible that the cork on top could ever get "sucked down", since you have an air stone pushing air out.
Perhaps your air pump isn't strong enough?

Sounds like you inlet side is plugged or the rubber cork on top is collapsing causing the rubber inlet tube to be pinched off when its installed.

Auto-Pilot, you were spot on! There was a massive amount of gunk in the attachment! Cleaned it out and it works like a charm!
