Aerated lagoon

An aerated lagoon is a kind of pond. It’s a big pool filled with water, but it has a few special features. First, it has special tubes that bring air below the surface of the water. This air helps to keep the water clean and healthy because it stirs up the water and mixes different parts of the pool. Second, sometimes special plants and fish are put in the lagoon. The plants use nutrients in the water to grow and the fish eat the plants or other small organisms in the water. With the air and the plants and fish, the water stays healthy and clean for a long time.
