What happens to pH levels as ammonia is converted to nitrate

As the pH rises, the concentration (toxicity) of the ammonia also increases. When the pH level increases above 9, most of the ammonium in the water is converted into toxic ammonia (NH3), which can kill fish. ... The Nitrobacter bacterium feeds on the nitrites in the water and converts them into nitrate (NO3).
