Any idea on how to tune this thing! It's a hydor external skimmer tons of bubbles are coming from the outlet, I got the whole setup 2nd hand. I know now the skimmer shouldn't be in with the return but it is now. What can I do to stop the bubbles in my tank half are coming from the skimmer and half are coming from the refugium weir! Doing my head in... Tank is 1 week old. Can see bubbles in the dt only when you put a light above!
I know the back knob changes water level that works fine. Font know assume is for air but doesn't do anything it's just loose.
