Neo Media Pure 5l - ceramic insert with neutral pH

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 the remarkable and diverse porosity but also by resistance to long-term use and, what is often underestimated, the impact of the inserts on the pH of the water.


pH tests of the water show that popular ceramic and ceramic-like inserts on the market have alkaline values, meaning they change 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 insert NEO MEDIA PURE 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 insert NEO MEDIA Pure does not change the pH, maintaining it at a level of 6~7. Additionally, the inserts NEO MEDIA come in three varieties: PURE, SOFT, and HARD, which respectively: do not change pH, soften water, and harden water.


The production process along with the fiber structure has allowed the creation of an insert that has varying pore sizes, enabling the settlement and rapid growth of different types of bacteria responsible for the transformation of harmful substances. The appropriate ecosystem developed within the insert is a decisive factor in biological filtration.
The diverse porosity is not available in ceramic inserts created by firing, where the pores in such inserts are always of the same size.


Advanced production techniques along with the fiber structure have achieved a record porosity that far exceeds the porosity of the best-known ceramics to date. (SIPORAX 270m2/l, Substrate PRO 450m2/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 period, complementing the most important advantages of the best biological insert in the world.

The excellent quality of the product 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 opinion issued by an independent group of researchers from Quantachrome.
