I have a Coral Life 125G protein skimmer of which I am using as a hang on back skimmer. My issue is I cannot get it to stop filling my entire tank with micro-bubbles. I have adjusted everything that was on the you tube videos with no luck. it said let it run for a while ant they will go away I ran for 4 days and they were going still full force. The fish do not like all the bubbles and hide in the farthest corner away from the skimmer. The good thing is after I run it the water is crystal clear and the cup has a good amount of debris. I now run it for a couple hours everyday and then shut it off. it was not cheap and I want to use it but not at the cost of making the fish uncomfortable. Help!!!
