I just purchased a 47 gal acrylic tank the I would like to set up as my first saltwater home. I'm getting confused on what to use for filtration. I would like some advice, please, on UV canister filters: whether or not to use a canister, and would I still need a skimmer?. The particular model my LFS recommended was the Aquatop-UV CF400. My ultimate goal is to have a colorful community of coral and fish. I plan to use live rock and live sand as well.
