Hey guys I've been reading up on some of this nano-saltwater tank articles and am concidering trying it out. I want a large salt eventually, but from what I've read this is the best place to start. What is the main things I need? I know a filter, powerhead, and lots of lighting is required, but does the filter need carbon just like freshwater? does the lighting need a hood (to prevent jumpers from escaping, I've seen many nano salts with just the lighting strip)? Protein skimmers, what are they and what are they used for? Live rock, I've seen tanks use a lot of this stuff, what is it? I'll stop there. I know I can find most of this stuff on the net and I'm currently looking at it, but I knw that here most of you guys have a good knowledge of this and would give me the fastest response w/ some of the best advice. Meanwhile I'm off to do more research! Thanks a lot guys!
