filter fleece and mats for mechanical and biological filtration

The porous material is penetrated evenly by the water and holds coarse and fine dirt particles.  After a short break-in time, the structured special foam is used to settle cleaning bacteria, which ensure intensive biodegradation of pollutants. 

The fleeces and mats are reusable.  For cleaning you should only rinse and express them, so that the bacterial cultures are not completely destroyed. 

• Porous material keeps coarse and fine dirt particles
• Good settlement conditions for cleaning bacteria
• Reusable For cleaning only rinse and express

SUBSTRATpro by EHEIM  

Optimized biofilter medium with perfect volume utilization, long service life and maximum degradation power

SUBSTRATpro by EHEIM consists of spherically sintered quartz.  The spherical shape allows a high bulk density.  Thus, the volume in the filter (filter baskets or modules) can be fully utilized.  In addition, the optimized surface of the beads ensures intensive settlement of the important purification bacteria.  It forms a dense bacterial lawn. 

The high number of bacteria also reduces nitrite exposure peaks and prolongs the service life of the filter material.  SUBSTRATpro by EHEIM is suitable for fresh and sea water, is washable and can be used several times. 

• Optimized sintered quartz bio-filter media
• High Bulk Density (globules)
• Very dense bacterial colonization
• Longer life Better nitrite stress reduction
• Multi-use (rinse gently for cleaning)
• Suitable for fresh and salt water
