I have heard a lot of good things about these guys, and they are very reasonably priced. So I am thinking of trying one out on my 240. BUT I don't understand what any of this means! I'm not very technically-abled.\r\n\r\n[url=http://www.aquacave.com/searchresult.aspx?CategoryID=222]Octopus Protein Skimmers - AquaCave[/url]\r\n[url=http://www.aquamartonline.com/1565.html]Products: ASM Skimmers[/url]\r\n\r\nWhich one would be the best for my tank? I need one that's in-sump. My biggest problem is I only have about 22" of clearance in my sump. Can any of these sit OUTSIDE my sump where I have more clearance and just have the water reach it through some plumbing or something?? HELLLLLPPPPPPPPP!!!!!!!!!!\r\n\r\nOh, and it seems that Octopus is a branch of ASM.
