How am I doing?

[ImBettaThanCool]

So I have just started the fishkeeping hobby about a month ago. I got some help starting when a friend of mine gave me a tank that was all ready. It was cycled, cleaned and treated. I was all set. Now, I have one betta fish in a Fluval chi 6.6 gallon tank. I have the marina 50 watt heater and the water is at a stable 77 degrees farenheit. I use tetra aquasafe and do 25% water changes a week. I use the API 5 in 1 test kit. I usually get GH of 80-120, KH of 80, PH 7.0, Nitrates 20, and Nitrites at 0. I feed my fish twice daily. 2 pellets in the morning and 1-2 in the night. So, how do you think I'm doing? Should I make any changes? Any tips or tricks?

Just keep up with the water changes and monitor the nitrites and nitrates for the next several weeks (and adjust water changes accordingly).
