Thanks for all the help guys! I will try my best to cycle my tank successfully. Wish me luck!
In the meantime, my new light fixture came in yesterday. It's a Jalli a18 with 55w compact fluorescent bulbs. I spent nearly $190 for the fixture and bulbs! And it took a week to come in. The box and receipt say its a 30" but it measures 29"

So it doesn't even fit on my 30" wide tank! What to do? If it's not one thing it's another...I wonder if the pet store will take it back after we assembled the fixture and everything...Plus, how would they be able to help if all they do is order it for me and the dimensions are supposedly correct, right? Order a fixture that's longer than 30"? (*sigh* Feeling discouraged...)
