BIO SPHERE 1L

Dymax Bio Sphere is a highly porous media designed as a substrate for biofiltration, specifically ammonia and nitrite removal (nitrification) and nitrate reduction (denitrification) for freshwater, marine and reef aquariums. This product cultivates nitrifying bacteria in its outer sphere and denitrifying bacteria in its inner part, thus providing exceptional efficiency for removing toxic substrate and preventing algae growth.
