ZEOLITE AND WATER FILTRATION                                                                                   Zeolite has a high
selectivity and capacity for ammonium via cation exchange capacity (CEC). Once the ammonium ion is within the
Zeolite lattice, it is not water-soluble. When used as an ion-exchange filter medium the Zeolite can reduce ammonium
content of circulating freshwater from aquaculture systems by as much as 97%. Piper and Smith (1982) suggested that a
water recycling system with a Zeolite filter system can allow up to a 10 fold increase in fish density. Zeolite also
reduces ammonium content in discharge waters in order to meet environmental requirements.
Zeolite is 100% natural, durable and can also be simply regenerated for repeat cycles of this ion exchange filter bed.
Zeolite can also be broadcast over the surface of a pond to be effective in reducing ammonium. The pond-bed sludge
can be recovered and used as a nutrient enriched slow release fertilizer.  The addition of Zeolite to ponds and tanks
also controls the growth of algae.
Zeolite provides a unique and simple way of removing algae buildup in your fresh water aquariums as well as cattle
stock tanks, ponds or other water holding facilities.  Zeolite does this by absorbing the Ammonia in the water that the
algae feed on; collecting the algae that is then attracted to the unique Zeolite pellets or rocks; and providing an easy
method for removing the algae from your aquarium.  We also provide you with a simple way of cleansing your Zeolite
that enables you to return it to your aquarium refreshed, to begin the algae prevention actions all over again
Zeolite is available in the form of decorative rocks or pebble size bedding and are packaged in various configurations
as follows: For larger aquariums or animal watering troughs, we recommend five pounds of Zeolite for each 75 gallon
capacity. For aquariums of smaller size, we recommend smaller Rocks of perhaps 1 to 3 inches in thickness, or no
more than six to eight ounces per 10 gallon capacity is usually sufficient to achieve the desired results. However, the
Rocks required will vary depending on the amount of ammonia being excreted in the aquarium by the fish.

Zeolite Filtration for Swimming Pools
Natural Zeolite is the new ideal filter medium for swimming pools in replacement of sand. Zeolite has many
advantages over sand due to its high porosity, durability and cation exchange capacity. Zeolite can remove
contaminants such as dissolved ammonia that sand and DE filters simply cannot handle.See also pool filters page.....
Advantages of using Zeolite
• Sand filters remove particles down from 100 to 40 microns in size. Zeolite  
filters remove  particles down to 3 microns,   which is equivalent to a DE filter. Dead skin and blood cells are smaller
than 9 microns  and cannot be trapped with sand or cartridge filters.
• Zeolite is a non-leaching, antimicrobial, and   will remove over 90% of viruses, bacteria, algae, and cryptosporidium
from your pool.   Zeolite reduces eye irritation. In addition to filtering skin and blood cells, Zeolite also absorbs
chloromines, nitrates, ammonia   phosphates, iron, manganese and filters giardia cyst and 75% of the bacteria known to
man. Zeolite is used to remove nitrogen, certain organic hydrocarbons, and toxic cations such as silver, mercury,
nickel, chrome, cobalt, antimony, arsenic and others.
• Dissolved ammonia reacts with chlorine to form chloramines which cause eye irritation and  odors in pool water.
Elites remove dissolved ammonium ions through ion exchange which neither sand nor DE filters can provide.
• Zeolite filters require fewer backwash cycles than sand filters. The backwash cycles are shorter therefore less water,
power and maintenance is required.  zeolites offer improved water quality, easier maintenance and reduced water
usage. zeolites also offer the added benefit of ammonia removal. Natural Zeolite is set to become the new swimming
pool filter medium for the 21st century.

FISH PONDS/AQUARIUMS
As fish feed, they naturally create ammonia that can quickly contaminate a confined aquatic habitat. Because of its high
cation exchange capacity,  Zeolite can be used to capture and bind ammonia in managed environments such as fish
farming, fish aquarium and fish transportation. To assist in keeping your fish pond clean and clear consider pumping
the circulating discharge through a simple packed bed of Zeolite. You should notice a dramatic difference after just one
day, the product is totally inert and will cause your fish no harm whatsoever, it will however remove a lot of the
suspended solids which your fish may rely upon for camouflage, so be aware of low swooping kingfishers
Additionally, where fish are processed for animal feed, in the USA 2% of Zeolite by weight (up to 20% in some other
countries) may be added to the feed to eliminate offensive odors.
Ammonia, the un-ionized form of ammonia (ammonia gas) is produced from the gills and urine from the fish as well as
from the bacterial decomposition of the unused food and fecal material. Fish utilize the nitrogen component of digested
proteins, the amino group (NH2) to build new proteins. However, when they utilize the proteins for energy, they cannot
metabolize the nitrogen, and the amino group is split off as ammonia gas. Ammonia gas solubilizes readily in water to
form ammonium ion. Ammonia is toxic and reduces the ability of the hemoglobin in the blood to hold oxygen.
Additionally, ammonia damages the gill structure, further impairing the fish in getting oxygen. Additionally, Zeolite is
especially adapted as a direct replacement for sand, sand and anthracite, and multi-media water filtration media as it
filters out particles as small as 3 microns, whereby sand typically filters particles of 20 microns or larger. zeolites’
unique crystalline structure will double the capacity to load particulate matter which will reduce the number of
backwashes required to keep the water clean and also acts as a biological filter in which bacteria mineralize the
organic nitrogen compounds, a process known as Nitrification. It involves the oxidation of ammonia to nitrite and then
to nitrates by autotrophic bacteria. The huge surface area of Zeolite makes it an excellent host for aerobic bacteria that
eat the ammonia. The zeolite will continue to remove algae for weeks on end, depending on the amount of ammonia
being excreted in the water over time. Once it becomes apparent that the algae are reforming in the aquarium or water
tank, you simply remove the rocks or bedding material and cleanse them thoroughly to remove the accumulated algae
and return them to the aquarium. They will immediately begin again to remove the ammonia and freshen and clarify the
water in your aquarium as before.
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).
Reduce  time spent cleaning your fish tank by mixing Zeolite granules into gravel or charcoal filter systems. Rinse
Zeolite first to remove any dust particles. Mix equal parts charcoal/zeolite in filtering system. If granules are too small
for placement in filtering system, place approximately 1/2 oz. of Zeolite in a breathable bag in the tank (1/2 oz. per 25
gallons of water). Make sure the breathable bag is safe for aquarium use. Replace when changing the filter or water.
Application
As with Activated Carbon, it's best to use Zeolite by forcing the water through a watertight container. You can use net
bags or other bags placed under water streams or falls.
You may use larger size which can be removed from the water, washed clean of the collected algae, and returned to the
water to continue removing algae.  Removal of algae reduces fish morbidity through providing cleaner and safer water
which enhances fish health.
