Ammo Rocks 10 lbs.

Natural zeolite ion-exchange resins that act like sponges to attract ammonia. Can be used as a biological filter substrate, or as a decorative finish to the bottom of your pond.

Ammo-Rocks are highly recommended as the perfect biological filter substrate in your filter. Ammo-Rocks provide the ideal home for nitrifying bacteria that help to speed up the natural balance. Ammo-Rocks are 100% natural zeolite. The growth of nitrifying bacteria is stimulated by the high surface concentration of ammonia on Ammo-Rocks. The nitrifying bacteria grow faster and produce larger and more active colonies for detoxifying ammonia, than with lava rock, gravel or bio balls. They are non polluting, safe and harmless to all fish, plants and invertebrates. 10lbs
