Why is my tank cloudy and green?
At the most basic, green aquarium water is caused by tiny bits of algae. These living bits are called phytoplankton, and you can only see them with a microscope. When phytoplankton become too concentrated in your tank, they’ll turn the water green, also called an algae bloom.
Why is my fish tank turning green so quickly?
