CrystalClear® Polish AC™ Activated Carbon



Lily Pond

CrystalClear Polish AC is bituminous coal that has been exposed to extreme heat which activates the carbon giving it potent absorbing powers. The billions of pores within the carbon act as hundreds of sponges soaking in many pond pollutants such as tannins, ammonia, nitrite, and nitrate. The result is a polished, healthy pond environment.

Routine Application Rate

Rinse carbon thoroughly before use. Remove the bag provided from the bucket and fill with the appropriate amount of carbon for your pond size or filter size. Then rinse the bag thoroughly to remove any carbon dust accumulation. Then apply to the filtration unit.

It is always best to use Polish AC in conjunction with a filter. It is not recommended to use Polish AC by itself within the pond.

Replace bag with new Polish AC carbon every 3 months. It is important to maintain fresh activated carbon especially throughout the spring and summer season when pond pollutants are at their highest levels.

Persistent Problem Application Rate

For large fish loads, it is advisable to double the amount of carbon for the pond size.

For Best Results

Make sure to rinse Polish AC carbon thoroughly before placing it in the filter. Never wash carbon after it has been in the pond with tap water. If carbon is washed vigorously dunk the bag in water with no chlorine present.

Product Notices:

Polish AC carbon can be disposed of with normal waste service.
