Evolution Aqua K+ Advanced Media 50L Sinking (Black)

Evolution Aqua K + Advanced Media is moulded with minerals for faster beneficial bacteria development. K + Advanced media also has a much larger surface area than any other media. Unlike foam, matting, or other forms of static filtration media, the K+ Advanced Media is designed to move freely within your filter in a downflow filtration system. The constant chaotic movement of the air from your pump causes the media to self-clean and thus requires no maintenance this allows the filter to reach optimum effectiveness without the disturbance of periodic cleaning, avoiding unnecessary loss of bacteria within the filter.
