I just got this skimmer today Octopus NW 150 Needle Wheel Protein Skimmer* - AquaCave
I was able to put it together by looking at that picture, since there wasn't much for directions in the box. My previous skimmer was a crappy airstone skimmer that was built into my wet/dry. What do I do with those foam donut things. I put them on there like in the picture. But, is the bottom one supposed to be flush with the water line? Also do you know how to adjust this skimmer? I just plugged it in and thats about it. The body of the skimmer has lots of turbulence but so far there is no foam or anything at all in the collection cup. I am assuming because of the whole break in thing. Thanks for any help.
