Is my water tank for a betta acceptable?

I'm starting a 2.65 gallon tank. I'm doing it completely from scratch (ie, without bacteria from an established tank or the addition of pure ammonia) and I'll add the betta cycle. I tested the water for only two days. I'm using the Aquarium Pharmaceuticals Freshwater Master Test Kit and the only product that I added that the water was Betta Water Conditioner Aquarium Pharmaceuticals. The first day (yesterday), my readings were as follows: pH = 7.4 to 7.6, ammonia = 0.25 ppm, nitrite = 0 ppm, nitrates = 0 ppm, temperature = 78 to 80 * F. The second day (today), my readings had changed: pH = 7.2 to 7.4, ammonia = 0.50 ppm, nitrite = 0 ppm, nitrates = 5.0 ppm, temperature = 78 to 80 * F. You may, however, I misread the color of the tubes were actually the first day and today is my actual results. Should only be worried about the ammonia? The Betta can get today and add to the tank or should I wait?

Everything looks good so far. Ammonia increased slightly lower pH, but is this normal during the cycle.
