Got my fish tank

On Friday I bought my aquarium! It's a 6 gallon JBJ nanocube. I'm already looking into how I can upgrade the lighting. I'm not if I'm going to need to upgrade the powerhead or not. Hopefully not. I'll be leaving the tank empty until next month because a) No more money b) Me and Natalie are going on vacation for a week at the end of the month and I want to be there when the tank cycles. I guess this will give me a good amount of time to make a choice about the rock and sand I'll use.
