Hornwort, coontail Certophyllum
Submerged plant that is bright green and feathery. Turns almost a black color in the winter.
Provides hiding places for the fish and a place for them to spawn (lay eggs).
Under water oxygenators also absorb dissolved materials in the water such as fish waste.
Helps keep the water clean and clear. Great plant for GREEN WATER
It is generally recommended that you place one bunch of oxygenators per 2 square feet of surface.
Hornwort is hardy to zone 5 and can be put in the pond once the water temperature reaches 55*.
If over wintered in a hardy zone in the pond, new growth will start when the water reaches about 62*.
