Aquarists are very passionate and opinionated about their skimmers. Perhaps it's just a mechanism to justify the large sums of money we spend on these devices. Regardless of the reason, there is a loyalty towards types and brands of skimmers that doesn't exist with other reef equipment. I've also avoided writing about skimmers because they're difficult to compare and "test." The best I can offer are my subjective opinions; although they're based upon having used or seen just about every skimmer offered for sale to marine aquarists.
