Coralife SS 220 hang on micro bubbles
 

Hi I was wondering how to stop microbubbles from my skimmer been running for 6 months now and it over flows every once in a while so I have to keep it on really low for out put also goes crazy with micro bubbles when I put frozen mysis shrimp.

Sounds like a good excuse to toss it and get a good brand of in-sump skimmer. Everything by coralife that I've used was a big disappointment. Horrible brand.
