Hornwort and algae
Hornwort has some ways to prevent the growing of algae in youre pond
or aquarium: Its poduces a substance to prevent the growing of algae
(this is called allelopathic behaviour). It grows fast thus blocking
sunlight that otherwise would be usefull for algae. It inhibits the
growth of algae because it consumes nutrients in the water.
It increases the PH of the pond or aquarium. It filters small
particels out of the water, making it more clear.
