My friend owns a LFS and I got to fool with a lot of different skimmers before deciding what to buy, and IMHO Coralife Super Skimmer has trhe best bang for the buck. While its usually common to hear you get what you pay for with lots of stuff, especially in marine fish stuff, even though this skimer costs less its still on par with some higher priced units. Seems the name on those high priced units do little if any to help in the simmer operation anyhow, but it makes some folks feel good they spent $350 instead of $150!
