Neo Media Soft Mini 5l - micro ceramic insert reducing pH

- the most porous insert
- lowers pH
- the most nitrifying bacteria
- small sizes
- 5 liters of this insert = 50 liters of another


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 the resistance to prolonged use and, what is often overlooked, the impact of 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 level, significantly hardening the water. (SIPORAX 9~10, Substrate PRO 8~9).

NEO MEDIA SOFT is a filtering material that lowers pH levels. It is suitable for all aquariums where the water pH is too high, such as: planted tanks, shrimp tanks, Malawi, Tanganyika, and marine aquariums with SPS corals.
The NEO MEDIA SOFT insert changes pH values by lowering them and maintaining them at a constant level, keeping it at 6~7.
The NEO MEDIA inserts are available in three variants: 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 with varying pore sizes, enabling the settlement and rapid development of different types of bacteria responsible for the transformation of harmful materials. The appropriate ecosystem developed inside the insert is a decisive factor responsible 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.

In the package, in addition to the insert, there are also nitrifying bacteria that accelerate the biological activity of the insert.

Advanced production technology along with the fiber structure has 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 up to 4000m2/l. Such a surface area along with varying pore sizes guarantees the best biological filtration.
The final stage 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.

MINI version:
It is dedicated to filters where there is not much space for filter inserts.

The excellent quality of the product is confirmed by research from the American research institute Quantachrome:
The NEO MEDIA inserts 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.
