Well, it's actually made up of millions of little bits of algae called phytoplankton.
It is the most common type of algae found in aquariums, garden ponds and natural environments.
Phytoplankton are tiny.
When they are few, these phytoplanktons give your aquarium a slight light green color that is not very disturbing.
But as they multiply, they transform the color of the water in your aquarium and cloud it.
See that green or yellowish cloud in your aquarium that gets thicker and thicker as the days go by.
It's when these phytoplankton gather in a large group that you first notice them in your aquarium.
The phytoplankton that turns your water green is so small that your filter is unable to retain it.
In fact, you can't see it with the naked eye.
To see phytoplankton individually, you need a microscope.
