I run a Reef Octopus only because it was the highest rated in the price range I was looking at when I got my tank. I knew very little about skimmers back then and have only had that one, but it has been a real workhorse and I am very happy with it. I have no experience with other skimmers so I have nothing to compare it to, but I am glad to see that it is the most popular brand here so far. Guess I made the right choice! ;Happy
