Huey Hung Genius Bio Sponge Filter 120L or 300L

Special multi-layer structure, natural sintering to 3D structure, combined with the super one sponge filter as the perfect oxygen dissolved filter.
1. Inner layer: Patented air cell structure to dissolve oxygen, compellingly separates water to supply lots of oxygen.
2. Middle layer: Uses natural Sedimentary Rocks, high temperature sintering leads to large number of multi-pores with 2D and three-dimensional structure. It is the best air-lift filter bio-implantation Porous biological technique filter media of its permeability. The surface area is 3-5 times of normal ceramic bio-filter. Establishes more stable water quality and ecological balance.
3. Outer layer: Pre-bio-sponge multi-layer design, hold pollutants to be clean the water quickly.
4. Attaches kinds of nitrifying bacteria that like toxins as their food. The rapid bacteria implantation forms a much better ecological balance for fish feed and reproduction.
5. Patented structure combines high nitrifying cultivating density, highly efficient power, long usage life and easy to be cleaned.

Experimental data
1. Porosity 30% above
2. Density 1.4g/cm3
3. Permeability 0.3cm/sec aboveAnimals & Pet Supplies
4. Pore surface area 20m2/g above
5. Water spreads evenly and stalls a long time (increase reaction between surface water and carrier of nitrifying bacteria).
6. Provide a wide range continuity of pores and rough surface.
