Provides deep anaerobic zones for denitrification.
Reduces nitrate more efficiently without harming the environment.
Consists of pearl-shaped inert ceramic.
Unbeatable surface area structure of 21260 sq ft per gallon.
Large pore structure to ensure optimum bacterial colonization and delays to the silting-up of the pores (for much longer intervals between cleaning.
Hollow cavity form a concentration difference of ions, NH4+ and NO2+ will adsorb actively to AC filter media.
Due to high concentration of bacteria,Peak ammonia and nitrite loads are more easily reduced.
Suitable for fresh and marine water, is washable and can be reused.
