RHS Galvanised 1 1/2 x 1 1/2 Patterned

Bio house ceramic media is 10X more effective than normal filtration by cultivating beneficial bacteria. It is heat treated at 1300 degrees Celsius for 60 hours that causes the ceramic to break its internal bonds leaving behind an 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. Dimension approx. Ideal for Pond; Freshwater; and Marine environments. PH Neutral. Reduces Ammonia; Nitrites & Nitrates. Improves Water Quality and Clarity at a rapid rate. Promotes Beneficial Bacteria Growth. Long lasting; highly porous ceramic material produces both mechanical and biological filtration.
