SUBSTRATpro

EHEIM SUBSTRATpro is a premium biological filtration media designed to deliver maximum efficiency and long term stability in freshwater and marine aquariums. Manufactured from high quality sintered glass, this advanced media features a highly porous structure that provides an exceptionally large surface area for the colonization of beneficial nitrifying bacteria.

Its optimized spherical shape ensures uniform water flow through the filter chamber, allowing consistent contact between water and bacterial colonies. This enhances the biological breakdown of ammonia and nitrite, helping to maintain balanced water parameters and support a healthy aquatic ecosystem for fish, invertebrates, and plants.

EHEIM SUBSTRATpro is suitable for use in external canister filters, sump systems, and multi stage filtration units. It integrates seamlessly with mechanical and chemical media to create a comprehensive and efficient filtration setup. The durable material ensures long lasting performance without altering water chemistry.

Ideal for aquarists seeking professional grade biological filtration, EHEIM SUBSTRATpro provides reliable performance, improved water clarity, and enhanced biological stability in both freshwater and marine aquarium environments.
