Inert Ceramic Material With Open-flow Architecture And Largest Usable Surface Area.Higher Efficiency Relative To Conventional Media, Efficiently Treating NH4-N And NO3-N.Most Technically Advanced Bio-filtration Substrate.The Surface Of The Spheres Is Microporous And Each Bio-Sphere Has Up To 54cm Squ Surface Area For The Establishment Of Bacterial Colonies. It Is Suitable For The Growth Of Various Microorganisms And Forms A Stable And Highly Active Bio-film On Its Surface.The Three-dimensional Void (3D) Formed By The Spheres Produces A Powerful Bactericidal Effect. They Are A Great Base For Sponge Growth, Micro-fauna And Coral Frags.Bio-Filter Sphere Will Work In Sumps, Trickle Filters, Wet/dry Filters, Hang-on Filters Or Directly In The Tank. It Can Be Used In Both Fresh Water And Seawater Environment.
