DESCRIPTION This ceramic media is 5X more effective than normal ceramic ring. It is heat treated at 1300 degrees Celsius for 60 hours that causes the ceramic to break its internal bonds leaving behind a extremely high amount of porous structure that has much greater surface to allow optimal amount of aerobic and anaerobic bacteria populations to colonize and thrive. Such conditions are crucial for the rapid breakdown of ammonia nitrites and nitrates to improve water quality. With the large amounts of tiny holes, mechanical filtration is also achieved. Large organic solids and decaying matter are degraded at a far greater speed than conventional media. Bio filtration does not build overnight. Please allow 7 to 21 days for beneficial bacteria to build and establish. Customers may use bacteria booster products to expedite the process. Please note: Fresh and saltwater have different bacteria type, please choose the correct bacteria booster for your aquarium.
