Expert Answer:

In a balanced, stable aquarium uneaten food or fish waste turns into ammonia. “Good” bacteria then convert these pollutants into non-toxic nitrates. Without regular water changes, the “good” bacteria will not be able to keep up with the accumulation of uneaten food or fish waste and the ammonia will quickly reach a dangerous level. This will drive down the pH level.
