Yeah, that's pretty normal. I spend AT LEAST an hour a day in front of the tank, and have since the day I set it up. Even if I don't have time...I make time.
Unless, of course, I'm on vacation...then I spend at least an hour a day worrying about the tank.
You don't really need any test kits beyond the standard right yet. pH, Nitrate, Nitrite, Ammonia, SG are the big things you're going to check for right now.
A RO/DI unit would be a wise investment, though.
