Just got this yesterday, and these are great skimmers for the money. My only problem is it sits in the sump right next to the return pump, and it produces a ton of micro bubbles out the bottom of the level adjustment tube. The result is a lot of bubbles entering the tank. There isn't room under it for a sponge, nor do I really like using sponges anyway. I tried putting a piece of mesh between the skimmer and pump, and that helped a little, but not much. I thought of maybe adding a couple of elbows to direct the outflow to the surface of the water, but not sure how that would affect things. Anyone have any ideas? The sump water is around 8" deep. I'm sure there's something obvious I'm just not thinking of, so that's why I'm asking you!
