Created over many years to keep the display ponds of the International Hardy Waterlily Collection free from algae. A unique unit that once placed into the pond, absorbs all impurities in the water, including those impurities that create green water and algae. Also reduces string algae. Ideal for freshwater fish including koi and goldfish.
