Hi everybody, I have a 6.7 U.S. gallon tank with one half moon betta in it. I've had the tank for a little over two weeks and I added Concentrated Aquarium Bacteria before I added my fish (Tetra SafeStart Plus). I've tested my water peramiters twice and both times the ammonia, nitrite, and nitrate have all registered at 0. shouldn't there be some nitrates by now? I'm using the API test strips. My fish is acting normal and his colors have gotten brighter since I got him.
