Use the passage below to answer the question.
As a fish-keeper or an aquarist, you may feel squeamish looking at the
murky discoloration in your aquarium. Can this foggy discoloration be
due to a bacterial bloom? In a word -- yes! Ensuring that the ammonia
and nitrite levels in your aquarium are at zero parts per million (ppm) is
significantly important in aquarium water upkeep. Excess food in the tank
begins to decay, causing ammonia and nitrates to build up, ultimately
leading to bacterial growth. To avoid this, make sure that you don't
overfeed your fish. Use an all-round test kit to check ammonia, nitrite,
and nitrate levels. If the ammonia levels are high, use an ammonia
removal product as quickly as possible. Change 30% to 40% of your fish
tank water every week.
