Even though you're adding ammonia during a water change, it's still important to do it to remove DOCs and to remineralize.
Using 2drop/gal Prime in your refill water will convert the ammonia. Use it every other day or whenever ammonia shows in the tank.
OK thanks....Ammonia is present at all times at .25ppm in the tank even after adding the prime....Im guessing this is just ammonium. I recently went to a planted tank as well. My readings yesterday before and after my 50% change of a 10g were A=0.25ppm NI=0 NA=5ppm. all levels were the same after the change and conditioner
