Elodea densa

It is a plant that reaches 50 cm. It is made up of several stems on which there is a multitudes of small elongated leaves measuring 2 cm by 1cm. Rapid growth plant, she is a very good exhaustist. Indeed, it absorbs the substances necessary for the growth of algae (nitritis phosphates, etc.) and thus participates in the ammisment of their presence. Unfortunately it only supports low temperatures.
