Ok I know people are always asking whats the best skimmer but for the most part everyone is looking for in sump or hang on skimmers. I have a 125 mixed reef display with a 55 gallon sump. I am running an ETSS 800 skimmer externally and I really like the external skimmer but the 800 just seams to maybe be over rated it doesn't run consistently on my tank. So my question is what are some good external skimmers out there to upgrade from the etss downdraft?
