Salvinia natans

Salvinia natans is a floating fern that grows quickly if there is sufficient nutrition and light. Light leaves are a sign of a shortage of micro-nutrients. Thin the plant to stop it taking light from the plants at the bottom. Salvina varieties have small hairs on their leaves, making them water resistant. Helps prevent algae by shading parts of the aquarium and using nutrients in the water. Grows very big in the wild and in optimum conditions. A decorative plant for open aquariums.
