Evolution Aqua K1 Media - Biological Filter Media Select Product:1 Liter 5' 1/4" and 3⁄8" SteppedMaturing the K1 Media bio media is important because a delicate eco system is naturally developing for the bacteria involved in the nitrification process. K1 Media provides the maximum active surface area for the bacteria to colonize, more than other types of static media. It is this process which removes harmful ammonia and nitrite from the water. As the K1 Media moves within the filter, it causes the old dead bacteria on the outside to be displaced.
