I wanted to raise the ammonia levels slightly to make sure the bacteria could continue to grow and thrive so I picked up some ammonia at ace hardware and dipped a qtip in the ammonia and then swirled it in the tank. There are about 10 ramshorns and 1 young guppy in the tank so I only wanted to raise the level to about 1 ppm and not to lethal levels for the inhabitants of the tank.
I was successful in raising the level to about 1 ppm and the nitrates test came back at about 1ppm as well.
