Oxygenating Plants

These submerged plants are useful in maintaining proper balance. They add oxygen to the water and serve as a filter by absorbing dissolved nutrients and thus compete with algae. They also serve as a green food source, spawning mat, and a hiding place for fish. The general rule for the amount of oxygenating plants to add to the pond is one bunch (about 3 sprigs) for every 2-3 surface square feet.
