CrystalClear Polish AC Pond Treatment 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.

• Activated carbon
• Removes tannins, chlorine and odor
• Polishes water and removes microscopic debris
• Removes ammonia, nitrite and nitrate
• Safe for all aquatic life
• Includes 1 mesh application bag
• Dosage Rate: Use 2.5 lb of Polish AC per 1,000 gal
• 5 lb treats 2,000 gal for up to 3 months
• Routine Application Rate: Replace bag with new Polish AC carbon every 3 months. Remove bag provided from bucket and fill with the appropriate amount of carbon for your pond size or filter size. Then rinse the filled bag thoroughly to remove any carbon dust accumulation. Then apply to 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.
• After 3 months Polish AC will have expanded and trapped so many pollutants that it will be time to replace it with fresh activated carbon. 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 thoroughly before placing in 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
