Hello everyone, I'm working on taking the plung into saltwater. I'v been a freshwater tank keeper for many years. My questions is this; after alot of research and looking I've found a 150 gallon tank with stand, 2x150 watts metal halide, pump, skimmer, refug and extra wet dry sump, and some live rock and sand, all for about 400.00. Is this a good deal? Thanks for any help and advice.
