Well there's good news and bad...
Good news is that you found this sight...
Bad news is that you haven't started a cycle yet. To put it simply a cycle is what we call it when your tank reaches an ammonia spike then a nitrite spike then finally a nitrate spike. This will happen in your tank and if you have fish in it, it could kill them. So right now, throw a piece of cocktail shrimp in your tank, let it rot, and your cycle has begun. After that, it usually takes about 6 weeks to complete, but you've added live rock so it may speed up the process. I know this isn't what you wanted to hear, but it's true.
