How do you fix green algae in a fish tank?
Using a solution of 5-10% bleach, dip the plants for a few minutes as needed to destroy the algae. Make sure they are thoroughly rinsed because bleach can kill your fish. Invest in a filter. Remember, if algae persist through regular water changes, you have to do more to combat the problem.
Why is my fish tank turning green so quickly?
At the most basic, the green is caused by tiny bits of algae. These flora 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.
