Why is it necessary to remove waste products from the aquarium?
      Waste products can cause the aquarium ecosystem to be out of balance. Solid and liquid waste products produced by fish contain ammonia, and can kill fish. Rotting food encourages excessive algal growth, which uses up the oxygen fish need to breathe. It is necessary to remove these waste products to maintain a healthy chemical environment inside the aquarium. Waste products are removed from the tank by using filters.
