This bottle green aquatic plant, also known as oxygen weed, is one of the few truly “true aquatic” plants on the market, meaning that it grows submerged under water throughout all seasons and does not survive out of water. Its fast growing habit means that it is an exceptional nutrient absorber for heavily stocked tanks, however it must be pruned regularly to avoid taking over.

Ensure all trimmings are disposed of responsibly, as it is a problematic weed in waterways. Elodea is a favourite snack for pet turtles.
