Zeolite in a 500g bag

Zeolite is a solid natural stone that contains many pores, cavities and channels.

Ideal for equipping UGF boxes or the pre-filter chamber of concave filters.

Zeolite is used in aquariums for various reasons:

1. Water detoxification: Zeolite is able to bind and remove pollutants such as ammonia, nitrite and nitrate from water. This improves water quality and reduces the risk of fish poisoning.

2. pH stabilization: Zeolite can help stabilize the pH level in the aquarium by buffering excess acids or bases in the water.

3. Odor elimination: Thanks to its adsorbent properties, zeolite can reduce unpleasant odors in the aquarium by binding organic compounds and waste materials.

4. Promote biological balance: Zeolite serves as a surface for beneficial bacteria that help break down organic waste and improve biological filtration in the aquarium.

5. Algae control: Zeolite can help reduce the nutrient supply of algae in the aquarium by binding excess nutrients such as phosphates.

6. Heavy metal removal: Zeolite can also help remove certain heavy metals from water by binding them and thus reducing their concentration.

Zeolite works adsorptively, meaning environmental toxins and decayed products are attracted and retained directly by the cavity system through strong electrostatic fields (e.g. up to 90% ammonia).

Zeolite has a huge internal surface area. Approximately 10 grams is the size of 4 football fields. The cavities are 4 millionths of a millimeter in size, a dimension into which an ammonia molecule fits exactly.

The phosphate content drops sustainably as the formation of natural bacteria and microbes is actively promoted. Zeolite acts as an ion exchanger and catalyst. The water becomes softer, clearer and free of toxins. Zeolite also promotes the rapid growth of bacterial cultures that convert nitrogen and fix and break down organic byproducts. 500g of zeolite is enough for 250 liters of water and remains effective for around 3 months with an average fish population.

TIP: Regenerate zeolite instead of replacing it! 

Saline method
To regenerate zeolite from the aquarium using table salt, you can follow the following steps:

1. Remove the zeolite from the aquarium and rinse thoroughly with clean water to remove any coarse dirt and debris.

2. Prepare a regeneration solution by making a mixture of water and table salt. The recommended concentration is usually 10% table salt, i.e. 100 g of table salt per liter of water. Make sure the salt dissolves completely.

3. Place the rinsed zeolite in a bucket or container and fill it with the prepared regeneration solution so that the zeolite is completely covered.

4. Allow the zeolite to soak in the regeneration solution for at least 24 hours. During this time, the salt binds pollutants in the zeolite and flushes them out.

5. After the exposure time, rinse the zeolite thoroughly with clear water to remove excess salt and detached pollutants.

6. Allow the zeolite to dry thoroughly before using it in the aquarium again. Make sure it is completely dry to ensure optimal adsorption performance. (Good results can be achieved in the oven at 60 degrees)

Regeneration with table salt is not as effective as other (expensive and complex) methods can be. Not all pollutants may be completely removed. It is recommended to replace zeolite regularly to maintain optimal water quality in the aquarium.
