Oxygenators

Key to keeping any pond healthy, oxygenators help to combat algae and blanket weed, keeping your pond looking clean and clear. They do this by absorbing nutrients from the water (needed for their rapid growth) and providing shade, leaving less food and light for algae to grow. These plants will be fully submerged in the water.

Ceratophyllum demersum

Hornwort
Summary Considered to be the best native oxygenator, hornwort is relatively slow growing compared to other oxygenators and doesn’t produce roots, making it low maintenance and easy to manage.

Hottonia palustris

Water Violet
Summary A great native oxygenator with feathery leaves and lilac flowers that are held above the water from June to August.
