Hornwort (Ceratophyllum Demersum) Is an amazing plant as it helps to add oxygen to the water while emitting a hormone to help eliminate algae. Grows well in full sun to full shade and grows in long, branching stems. Hornwort grows quickly and helps to clarify the water as you see in the photos, it is very easy to grow and can be tucked into the substrate at the bottom of the pond, weighted with small anchors or allowed to float. Also great for spawning or cover for small fish.This underwater oxygenating grass is the best plant to compete with algae and keep a happy clean pond. Other benefits include being a sanctuary for fish from predators and fish fry when young.



Plant hornwort in the substrate on the bottom of your pond or plant in small containers using clay planting medium or sand. Hornwort may also be anchored with small weights.
