Submerged plants are one of the best plants for helping to balance the pond's ecology.They absorb nitrogen, provide shade, food, cover, and a spawning medium for fish. They release oxygen into the water daily, but they consume oxygen at night. Although they are not capable of correcting an oxygen problem in a pond, they will help improve the health of the pond.

Use planting media and planting baskets for best results.
