There really aren't any "experts" at the petsmart or petco I have seen. They are salesman remember that.
Nitraban may work only time and lab testing will tell. I personally own this product and have found it mildly useful If I have to stretch a water change over a week. But thats only happened twice. So my advice if you are leaving for a week and you havent changed water in a week and cant change it. Dose with easy balance. Its a good tool to have in the shed I know that much.
