Description
MarinePure® Biofiltration Blocks – The Complete Nitrification & Denitrification Solution
Advanced Biological Filtration for All Aquatic Systems
Specially engineered ceramic blocks providing dual-action water purification:
✔ Eliminates Ammonia/Nitrites (aerobic nitrification)
✔ Reduces Nitrates (anaerobic denitrification)
✔ Works in Freshwater & Saltwater
✔ Perfect for Sump or Wet/Dry Filters
Unmatched Performance
8"x8"x4" Block Features:
• 139,800 ft²/ft³ surface area – 1,400x more than bio-balls!
• 80-90% open porosity – Allows deep anaerobic bacteria colonization
• Ultra-lightweight (0.3-0.5 g/cc) yet durable
• Chemically inert – Won’t alter water chemistry
Flow Recommendations:
→ Fast flow = Maximum ammonia/nitrite removal
→ Slow flow = Enhanced nitrate reduction
