Neo Media Soft 5l - ceramic insert that lowers 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 the resistance to prolonged use and, what is often underestimated, the impact of the inserts on the pH of the water.


pH tests of the water prove 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 SOFT is a filtering material that lowers the pH value. It is suitable for all aquariums where the water pH is too high, such as: planted tanks, shrimp tanks, Malawi, Tanganyika, and marine tanks with SPS corals.
The NEO MEDIA SOFT insert changes the pH values by lowering them and maintaining them at a stable level, keeping it at 6~7.
The NEO MEDIA inserts come in three variants: PURE, SOFT, and HARD, which respectively: do not change the pH, soften the water, and harden the water.


The production process combined with the fiber structure has allowed for the creation of an insert that has varying pore sizes, allowing for the settlement 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 in biological filtration.
The 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.

The advanced production technique 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 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, 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 NEO MEDIA inserts were tested by the Quantachrome Corporation laboratory on Quantachrome Instruments. All product data is provided based on the opinion issued by an independent group of researchers from Quantachrome.
