On a whim I picked up a bag of salt, a bag of bio sand, and broke out my old freshwater stuff. So far my tank is just fish, blue leg hermit and an emerald crab in there.. with a desklamp and 2 little HOB filters. Also some cheesy neon decorations. Haven't tested for jack.. don't even have a thermometer! :P

Should I be testing the water for TOD, hardness and pH? Before getting in to "live deco" like macros or polyps anything else? Should I get a skimmer? I'll dig through this section of the forum.. but any advice is appreciated!
