EHEIM SubstratPro Biological Filter Media 720g
EHEIM SubstratPro Biological Filter Media 720g is a premium sintered glass media designed to maximize biological filtration in both freshwater and marine aquariums. EHEIM Substrate Biological Filter Media 720g features pearl-shaped beads that provide a high bulk density, allowing for full use of the filter volume while offering an optimal surface area for the colonization of beneficial bacteria. This high bacterial density enhances the breakdown of nitrites and other toxins, extending the time between cleanings and improving overall water quality. Washable and reusable, it fits perfectly in filter baskets or modules and supports long-term stable biological filtration.

EHEIM Substrate Biological Filter Media 720g
Optimized bio-filter medium with perfect volume usage, long intervals between cleaning and top decomposition performance.
SUBSTRATpro consists of pearl-shaped sintered glass. The spherical shape gives a high bulk density. Thus the whole of the volume in the filter (filter baskets or modules) can be utilized. Also the optimum surface of the beads provides intensive colonization of the important purification bacteria.
Due to the high number of bacteria, peak nitrite loads are more easily reduced and the maintenance intervals of the filter material are longer.
EHEIM SUBSTRATpro is suitable for fresh and marine water, is washable and can be reused.
- Optimized bio-filter medium made from sintered glass
- High bulk density due to spherical shape (beads)
- Very dense colonization of bacteria
Helpful Tip:
Never clean or change all the filter media together in one operation, and never clean too thoroughly. The bacteria culture must not be completely destroyed, otherwise recolonization will be compromised.
