Neo Media Hard 1l - ceramic insert for raising pH

The manufacturer of NEO MEDIA inserts has made every effort to create the best biological insert in the world.
This status is determined not only by the remarkable and varied porosity but also by the resistance to long-term use and, what is often overlooked, 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 HARD is a filtering material that raises the pH value. It is suitable for all aquariums where the water pH is too low, such as: planted tanks, shrimp tanks, Malawi, Tanganyika, and marine tanks with SPS corals.
The NEO MEDIA HARD insert changes the pH values by raising them and maintaining them at a constant level.
The NEO MEDIA inserts 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 different pore sizes, allowing for the settlement and rapid development of various 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 through firing, where the pores in such inserts always have the same size.

The package contains not only the insert but also nitrifying bacteria that accelerate the biological activity of the insert.

Advanced production techniques along with the fiber structure have achieved 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 4000m2/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 NEO MEDIA inserts were tested by the Quantachrome Corporation laboratory using Quantachrome Instruments. All product data is provided based on opinions issued by an independent group of researchers from Quantachrome.
