Eheim Aquarium filter accessories Substrat Pro 5L

Optimised filtration substrate with perfect volume use, long-lasting and very high degradation capacity. SUBSTRATpro is made of sintered quartz in the form of beads. The spherical shape allows for a high density. This means you can utilise the entire volume of the filter (baskets or filter modules). Additionally, the optimised surface of the small beads ensures intensive colonisation by beneficial cleaning bacteria. A thick bacterial layer forms. The high number of bacteria helps to better reduce spikes in nitrate levels and extends the lifespan of the filtration material. EHEIM SUBSTRATpro is suitable for freshwater and saltwater, is washables and can be reused multiple times.
