Mojo, any thought on the SWC 160 cone with the hybrid impeller? I didn't check every post on this thread so I'm not sure if you mentioned anything on it. I am using it right now on my 120 light to med stocked mixed reef. I chose the 160 because of height restrictions, cost, performance, and ease of use/maintenance. I'm extremely happy with the 160 and believe it's the best bang for the buck skimmer.
