Oxygenators

These are, for the most part, submerged plants. They are very useful in supplying cover for aquatic insects and lavae and because they are fast growing will take up alot of nutrients from the water, thereby reducing algal growth.

They produce oxygen during daylight hours but as they take oxygen out of the water at night they should not be planted too densely.

Some oxygenators are not advised for large earth ponds as they can become invasive.
