Why is excessive algal growth a problem?
      When the water is rich in nutrients from too many fish and the lighting is strong, it may result in the excessive growth of algae. A large number of algae in the tank compete with oxygen producing plants for the nutrients, light and oxygen. Excess algae may appear as green tinted water or hairy growth around the aquarium. That is why it is important to control the amount of light and to make sure that the waste produced by fish is removed promptly.
