I have a Reef octupuss elite 150 sss and i am having trouble dialing it in. It seems to have way too many bubbles comming out of the output. If I turn the pump speed down the bubbles dont reach the collection cup unless i open the volute, but then i get too many micro bubbles from the output. If i increase the pump the i have to dial the volute down and then the water level rises to just below the top of the collection cup and i have micro bubbles still.
