• 1 pieces of bio block
• Dimensions of each block: 20x20x5 cm

• Biological filtration is a critical process in any aquatic environment.
• outperforms other filter media in terms of removal of fish waste and organics, as well as in term of its clog-free design.
•  made of durable hardened ceramic, with an ideal ratio of surface area to void space for optimum gas exchange, whereby beneficial bacteria can colonise .
•  break down ammonia, nitrites as well as nitrate quickly and effectively.
• can be used in sump filtration systems, OHF, refugium, including wet/dry filters.

BENEFITS

• Made of inert, 100% pure ceramic, kiln-fired and hardened for durability and long life.
• Clog-Free design with natural random channeling of water.
• Porous filtering surface allows maximum aerobic bacteria colonisation.
• 300% more surface area than all traditional ceramic filtration media.
• Has the ideal ratio of surface area to void space for optimum gas exchange.
• Water channeling throughput rate is optimised with the bio-filtration rate.
• Accelerates the breakdown of ammonia, nitrites and nitrate.
• Does not alter water pH.
• Can be washed and reused.
