The inside structure filter media are all connected , the surface are of every gram filter material can be 4m2. Effective using rate 98%• Ultra high surface area and open porosity • Eliminates ammonia and nitrites and minimizes nitrates • Specifically designed for the high flow of koi and goldfish ponds and aquaculture systems. • Use in sumps, extra-large filters , shower filters and waterfall filters etc • Lowers pond maintenance and improves water quality •Allows for higher fish loads High adsorbabiliity , which can obviously accelerate the adhesion of nitrifying bacteria and mass propagation , increase build nitrification system .
