Eheim Filter material

Eheim Substrate is a high-quality filter material for aquarium filter systems, available in a 5-liter package. This filter substrate is made from crushed glass and can be used in multiple layers within the filter compartment. It serves as a standard, highly porous filter material with an optimized surface structure that provides a large area for the colonization process of beneficial bacteria, which is essential for biological filtration in aquatic environments.

Suitable for freshwater and saltwater aquariums, this substrate is washable and reusable, allowing for long-term use. The product dimensions are 20.2 cm in length, 18.6 cm in width, and 22.2 cm in height for the packaging, with a package weight of 1000 grams. As filter material model 2509751 with MPN H2509751, it represents reliable filter technology from the established brand Eheim.

For optimal aquarium care, it is recommended not to clean or replace all filter materials at the same time to preserve established bacterial colonies and maintain stable water parameters. This substrate contributes to effective biological filtration by supporting nitrifying bacteria that process ammonia and nitrite, thus helping to create a healthy aquatic ecosystem.

The crushed glass composition ensures even water flow through the filter while providing sufficient surface area for microbial growth. Its neutral pH properties make it compatible with various aquarium setups without affecting water chemistry. The reusable nature of this material allows for cost-effective filter maintenance over extended periods. Properly integrated into filter systems, Eheim Substrate supports clear water conditions and stable biological filtration processes that are essential for aquarium health.
