Just keep testing your water regularly like you have been and do a water change when anything creeps up a bit more than it should.
Sounds like you're on your way to being cycled. Tanks rarely need anything other than water conditioner added to the water, try to avoid using any of those other chemicals... as you've already seen they typically do more harm than good. In the long run the best way to keep your tank's water healthy is just good ol' water changes and filtering.
