Neo Media Pure Quad 1l - ceramic insert with neutral pH

- the most porous insert
- neutral for water pH
- the highest amount of nitrifying bacteria
- 1 liter of this insert = 10 liters of others
- bacteria included for free

The manufacturer of inserts NEO MEDIA has made every effort to create the best biological insert in the world. This status is determined not only by its remarkable and diverse porosity but also by its durability during long-term use and, what is usually overlooked, the influence of inserts on the pH of water.


Ceramic inserts change the pH of water! Did you know that?
pH tests of water show that popular ceramic and ceramic-like inserts on the market have alkaline values, meaning they alter the pH value, significantly hardening the water. (SIPORAX 9~10, Substrate PRO 8~9).
NEO MEDIA PURE is a truly neutral filtering material and has a minimal impact on pH. The NEO MEDIA PURE insert does not raise the pH of slightly acidic aquariums and does not lower the pH of slightly alkaline aquariums. It is suitable for all types of aquariums, such as: planted, shrimp tanks, Malawi, Tanganyika, and marine aquariums with SPS corals.

The NEO MEDIA Pure insert does not change the pH, maintaining it at a level of 6~7. Additionally, NEO MEDIA inserts come in three variants: PURE, SOFT, and HARD, which respectively: do not change pH, soften water, and harden water.

Diverse porosity:
The production process along with the fiber structure has allowed the creation of an insert that possesses varying pore sizes, enabling the settling and rapid development of different types of bacteria responsible for the transformation of harmful substances. The appropriate ecosystem developed inside the insert is a decisive factor for biological filtration.
Diverse porosity is not available in ceramic inserts created through firing, where the pores in such inserts always have the same size.

Largest surface area:
Advanced manufacturing techniques combined with fiber structure have achieved a record porosity that far exceeds that of the best-known ceramics to date. (SIPORAX 270m2/l, Substrate PRO 450m2/l, Matrix 700m2/l)
NEO MEDIA offers as much as 3600m2/l. Such a surface area along with varying pore sizes guarantees the best biological filtration.
The final phase of production ensures the durability of the product for a long time, completing the most important advantages of the best biological insert in the world.

Excellent product quality is confirmed by research from the American research institute Quantachrome:
The inserts NEO MEDIA were tested by the Quantachrome Corporation laboratory using Quantachrome Instruments. All product data is provided based on the opinions issued by an independent group of Quantachrome researchers.

Bacteria included:
In the box, there is a separate package containing nitrifying bacteria that accelerate the quick start of the ceramic. They appear as small black balls. Sprinkle them between the ceramics in the filter.
