About This Item

Details

  • This media is made from safe, inert ceramic material that does not alter water chemistry.
  • The deep pore structure with interconnected micro-tunnels offers a vast surface area for biological activity.
  • Linked cavities allow for free and even water flow, preventing blockages and prolonging contact time for superior filtration.
  • This media helps establish a high concentration of biological activity to quickly and efficiently reduce ammonia and nitrite for a healthier aquarium.
  • For best results, rinse monthly using aquarium water and replace partially every 6 months.
