Moving Bed K1 – High-Performance Biological Filter Media
K1 is a high-quality biological filter media designed for use in Moving Bed Biofilm Reactor (MBBR) systems. It is specifically engineered to provide a large surface area for the growth of beneficial bacteria that support efficient water filtration.
With its small circular shape and specially designed internal structure, K1 offers a specific surface area of up to ~800 m²/m³, allowing microorganisms to effectively break down waste substances such as ammonia (NH₃) and nitrite (NO₂⁻).
✅ Key Features:
  
High surface area → Supports a large population of beneficial bacteria
  
Self-cleaning motion → Minimizes clogging and reduces cleaning frequency
  
Ideal for koi ponds and RAS systems
  
Perfect for biological filtration in aquaculture and ornamental fish ponds
