In all respect to the original poster i think we are getting a little off topic.
Texanboy, as far as your tank being cloudy that happens when you add sand and its no big deal it will clear up. As far as starting the nitrogen cycle in your tank you can add a raw uncooked shrimp, fish food, live rock (this was my method for my tank), and as above some add fish. Besides the debate over whether or not its cruel to add fish another point is because ammonia is toxic to fish it can kill the fish you put in there so why waste the money and trouble of catching that fish and having to return it if it is one you don't want anyways. As far as alot of other questions you may have while waiting for replies read through the archives forum where you will find alot of answers. Also research and patience are key so two great books i can recommend are "the Conscientious Marine Aquariest" by Robert M. Fenner and "The New Marine Aquarium" by Michael S. Paletta. These books cover almost everything from tanks, equipment, fish, corals, maintenance, and alot more. They also have step by step guides on setting up a new aquarium. So by reading one or both books and then asking here about certain questions you have, about what you've learned, here it will make your life a lot easier with your initial setup. I hope this helps and remember the only stupid question is the one that goes unasked. reasearch and patience!!!
