Bubbles from my skimmer

[madpigeon228]

I have had a Euro Reef 6-1 skimmer for the past 6 months, everything has been great until last night. The skimmer is returning micro bubbles into my sump that ends up in my tank. I cant figure out how to fix the problem and I was hoping that some of you could help.

Thank You

Could the venturi be getting clogged? That woud make the pump pull less air and more water, increasing flow through the reaction chamber, possibly pushing bubbles into your tank. Try running some ro/di water through the hose
