Hello, I use a Deltec 2060 in a new 125g tank and my question is what I have done wrong that I have soo many air bubbles from the outlet. I know that a new tank with a new skimmer can produce air bubbles but I don’t think it’s that because I have same air bubbles amount even if the air pump of the skimmer is off. I posted a picture with air pump off and a lot of air bubbles. I don’t think I have any air liking in the plumbing connection because I don’t see how. I use a Eheim pump to feed the skimmer like you see in the picture. I run this skimmer 20 days and same problem. The pump you see in sump and the rubber hose goes to the skimmer. What can be???
