It could be that the outflow port (tube) on the bottom has twisted, not allowing water to flow enough to drop the level? You'll have to hold the air intake in place and carefully twist the tube until it's in the right position. I think the water height should be 21cm or 8" on the 120? I'm not sure how long yours has been running, but it may take days for it to build up enough biofilm and settle down?
Yup that did it! Also i figured out it was in too deep of water so I raised it up about 2 inches. There is some sludge caught in that main tube though, is there anyway to completely detach it from the skimmer for cleaning?
