API Bio-Chem Stars biological media provides a nurturing environment for the growth of beneficial nitrifying bacteria in your aquatic ecosystem. The bacteria transform harmful ammonia into nitrate, a natural process known as the nitrogen cycle. As your aquarium matures, these bacteria thrive on the surface of aquarium gravel or in filter media such as API BIO-CHEM STARS, thanks to its unique 50-70 micron internal pore size, specially designed for optimal oxygen and water transfer. This patented production process results in 4 times more surface area for bacterial colonization compared to ceramic rings.

Instructions:

Rinse thoroughly to remove any dust. Place BIO-CHEM STARS biological media in the last compartment of your filter. Bio-Chem Stars biological media will become colonized by bacteria within several weeks.
