I was thinking about setting up a 10 gal saltwater tank with some sand and live rock, letting some algaes and whatnot grow. I've never done salt before, and I was just wondering what people would suggest as far as filtration for a small tank like that. How well the hang-on nano skimmers work? I also would appreciate any suggestions on fish or other creatures. I realize that I wouldn't be able to put much in there. Thanks.
