Can I sneak a quick question in here about mine too? First time ever using a skimmer (never did in FW tanks) and I have the SWC 150. I'm in 9" of water (8"-10" recomended) and I don't know how to dial this in right. I ran it wide open for a few days to "break it in" as people had suggested, but I don't know what level to set the bubbles to rise to, and how much air to let in. I don't have a bioloaded tank as of yet so I don't expect heavy skimmate, but should I be getting anything yet? I have brown algae (diatoms?) growing on all the rocks now and my live rock had coraline and green algae (unknown?) when I bought it. In the pictures, how high should I have the bubbles at? If I open the muffler (as I read it called in here) all the way the bubbles overflow, if I shut it down, no bubbles.
