Overview

  Zeolites have many useful purposes. They can perform ion exchange, filtering, odor removal as well as, chemical sieve and gas absorption tasks. In a similar way, zeolites can absorb ions and molecules and thus act as a filter for odor control, toxin removal and as a chemical sieve.  Zeolites added to livestock feed have been shown to absorb toxins that are damaging and even fatal to the growth of the animals, while the basic structure of the zeolite is biologically neutral. Most municipal water supplies are processed through Zeolites before public consumption. 

Pond Use 

  Available in Aquaculture supply houses in bulk form, most pet shops in the expensive form. Pond hobbyists are seeing more Zeolite products in pond stores, as Zeolites make excellent removers of ammonia and other toxins. 

  High water temperatures and high PH levels will generate higher Ammonia Levels. 

How Much to Use

  1 gram of Zeolite will remove 1.5milligrams of ammonia from a liter of water. Take an Ammonia reading of your pond in PPM (parts per million). Divide by 1.5. Multiply by the numbers of Liters in your pond (3.78 Liters = 1 Gallon). The final volume is the number of grams needed to treat your pond (1 level teaspoon of Zeolite equals 7 Grams).

Application

  As with Activated Carbon, it's best to use Zeolite by forcing the water through a watertight container. Although not as efficient, you can use net bags, or any perforated containers placed under water streams or falls.

Recharging Zeolite
  You can also recharge Zeolite to about 78% of it's normal adsorption rate by soaking it in a salt water solution (1lb. of salt to 3 gals. of Water) for 9 hours or more. Remember to rinse the Zeolite before returning it to the pond.

Caution-- Salt will cause Zeolite to release the ammonia back into the pond water column after adsorption capacities are full. If you need to use Zeolite in a salted pond, make sure it is unused and fresh.
