ZEOLITE GRANULES MEDIA BAG
- Zeolite can remove ammonia effectively in a very short of period, it is often used as an emergency solution to quickly remove ammonia. When you have a sudden rise of ammonia because of a bio filtration system crash or overfeeding, adding zeolite together with large amount of water change can save your precious fish a lift.
- 1 gram of zeolite will remove 1.5 mg of ammonia. For example, to remove 1 ppm (1 mg/L) ammonia from 10 gallons (38 liters) of water, use a minimum of 25 grams (.13 lbs) zeolite (38 mg 1.5 = 25).
- Zeolite can be recharged by the use of ordinary table salt. Take a liter of 5% solution of Salt water and soak the zeolite in it the brackish water for 24 hours. Then rinse afterwards. Salt will cause the zeolite to release the absorbed ammonia back into the water. That’s how the zeolite is “recharged”. For the same reason, you should not use salt when there is zeolite in the tank or filter.
- Zeolite, is an effective means of removing ammonia. Ammonia is the most prevalent cause of tropical fish loss. The presence of ammonia increases fish’s susceptibility to disease and infection and drastically reduces their oxygen carrying capabilities. A quantity of the zeolite are placed in a media bag so it can be removed afterwards or simply scattered into the tank as the rock is harmless if left permanently. It will provide a large surface area for nitrifying bacteria. So zeolite can also be used as a bio-filtration media.
What Is Zeolite?
Zeolites are highly absorbent porous minerals, composed largely of silica and aluminium. They are useful for their ability to capture and hold a variety of undesirable materials, much like a sponge absorbs water. However, not all zeolite is created equal. How the zeoilite was formed impacts it’s makeup, and consequently which applications it is best suited for. Clinoptilolite, or Clino, is a naturally occurring form of zeolite that has a particularly high affinity for ammonia, making it a desirable media material.
When choosing zeolite for your aquarium, select one that is labeled for specifically for aquarium use. For instance, most cat litter contains zeolite, however it’s not formulated for aquarium use, and I would not recommend using it. There is zeolite formulated specifically for freshwater aquariums, as well as for both freshwater and saltwater aquariums. Either formula is suitable for freshwater aquaria. There are also some formulas available that combine activated carbon and zeolite, a combination that is well suited to a newly set up aquarium that is experiencing a severe ammonia spike.
Zeolite formulated for freshwater aquarium use will readily adsorb ammonia, making it a useful media when dealing with ammonia spikes or potential spikes. It is important to know that zeolite does not remove every undesirable toxin in your tank, nor does it work forever. In fact, it becomes saturated fairly quickly, at which point it no longer provides any benefit. Generally within a month or less it is exhausted and should be replaced or recharged. In cases of extremely high ammonia levels, the zeolite may become exhausted in two weeks or less. When ammonia levels are elevated, always test frequently, replacing the zeolite as needed to until the desired results are achieved. Once the ammonia has been eliminated, remove the zeolite.
Experts disagree on the value of using zeolite in a newly set up aquarium. As a general rule it is recommended that the biological balance in your aquarium is allowed to develop naturally . However, if an dangerously high ammonia spike should occur, the use of zeolite on a short term basis is warranted. This is true even in a newly set up aquarium, as ammonia poisoning can quickly prove fatal in those situations. It is advisable to remove the zeolite once the ammonia levels drop. Zeolite should not be used on a permanent basis, as a well functioning biological filter should eventually take over that role. Instead it should be removed and replaced with standard media, such as activated carbon.
Zeolite formulated for freshwater should never be used in saltwater or brackish tanks. The effect on the water chemistry can be lethal for corals in saltwater aquariums. Nor should salt be added to a freshwater aquarium when zeolite media is already being used. Adding salt can cause the zeolite to release the ammonia it has absorbed, causing a sudden and potentially dangerous ammonia spike.
The Zeolites commonly used in freshwater adsorb ammonium, which is a desirable function in fresh, AND seawater. However, Zeolites do prefer calcium. This is a big problem for seawater when calcoim levels are being depleted by the Zeolite. There is usually little to no calcium in normal freshwater, so the Zeolites absorb ammonium. Because there is a lot of calcium in seawater and because these specific Zeolites prefer calcium, the calcium values drop instantly, with sometimes catastrophic results. In the earlier days, when marine aquarists experimented with freshwater Zeolites, they ended up with very low calcium concentrations of less than 200 mg/l.
