Help with Bubble magus BM 100 SE

[Tom Giddens]

I need help from someone that has one of these and knows how to operate. There were no directions where to start and I have no idea what the knob does and on the opposite side the is a wheel with numbers at the bottom of the skimmer. This is my 1st BIG BOY skimmer, the previuos ones were HOB and all you did was adjust the hieght of the cup and adjust the air intake.

I don't have this exact model but looking at pics the knobs on both sides should open and close the outflow valves on the bottom of the skimmer which will control the water/bubble level inside the skimmer body. The settings will depend on water level in your sump so adjust slowly to get the bubbles popping near the neck of the skimmer for a dry skim or halfway up the collection cup for a wet skim.
