High Grade Bio Ring Bio Filter 500g

one pack: 500g

– The ring shape allows for water to flow through the biofilter media.
– Their internal porous system, like the Seachem Matrix BioMedia (see below), help more bacteria to grow than smooth biofilter media do.
– Replace BioMax Insert every three months.
– They are typically used in fish tank and fish pond filters to transform potentially harmful ammonia into benign nitrates.
– Bio balls are spheres consisting of tiny tubes that provide a large surface area on which water-filtering microbes can grow.
– If you notice a thick green or brown gunk coating your bio balls, then you need to clean them. Cleaning bio balls is best done during a water change.
