Eheim SUBSTRATpro is Eheim’s best biological filter media. This is a pearl shaped, highly porous filter material made from sintered glass and it has a large surface for bacteria to colonise (450 m² per litre). The pearl shape enables the water to flow through the media easier, reducing dead spots and making the media more efficient. Suitable for use in external canister, sump, Aquaball and Biopower filters.

SUBSTRATpro needs to be placed in the filter after the mechanical media and can be built up in one or more layers. SUBSTRATpro is washable and can be used several times. Suitable for both fresh and saltwater.

With the high number of filter bacteria, peak nitrite loads are more easily reduced, and the maintenance intervals of the filter material are longer.

Top tip:

It is advisable that you clean the filter medias in old aquarium water during maintenance. Do NOT clean the filter medias in tap water as chlorine and chloramines will remove the beneficial nitrifying bacteria that have colonised during the maturation of the aquarium.

EHEIM filter medias are some of the best in the world. They are highly efficient, developed in their own research laboratories, and made from the best raw materials. They are continually checked and are guaranteed to be free from any harmful substances.
