is excessive algal growth a problem?
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.
