EHEIM SUBSTRATpro 720g ≈ 1l filter media

EHEIM SUBSTRATpro Enhanced bio-filter medium designed for optimal volume usage, extended durability, and exceptional degradation efficiency. SUBSTRATpro is made from spherically sintered quartz. Its rounded shape enables a high bulk density, ensuring that the entire capacity of the filter (filter baskets or modules) is effectively utilized. Furthermore, the optimized surface of the beads promotes a robust settlement of essential cleaning bacteria, resulting in a dense bacterial lawn. The abundant bacteria population effectively mitigates nitrite load spikes and prolongs the lifespan of the filter material. EHEIM SUBSTRATpro is compatible with both freshwater and seawater, can be washed, and is reusable. Optimized bio-filter medium made from sintered quartz High bulk density due to the spherical shape (beads) Very dense bacterial colonization Extended service life Improved degradation of nitrite contamination Reusable (rinse gently for cleaning) Suitable for both freshwater and seawater Biological filter media The primary function of biological filter media is to create optimal conditions for the growth of bacterial cultures, allowing a bacterial lawn to establish quickly. These bacteria consume various dirt particles and transform substances that could be harmful to the aquarium. After the initial cleaning phase with mechanical filter media (such as EHEIM MECH or MECHpro), biological filtration is crucial. It guarantees clear, healthy water and stable water parameters. This is why we have dedicated substantial research efforts to the advancement of biological filter media. Tip: Avoid cleaning or replacing all biological filter media at once (and refrain from excessive cleaning). It's vital to preserve the bacterial cultures, as complete destruction would delay re-colonization. The filter baskets in external filters and the filter modules in the aquaball and biopower internal filters are perfect for partial cleaning.
