KaldnesŪ BiochipThe Biochip is much more than just a different shaped media. In addition to having a total protected surface area more than 2.4 times that of Kaldnes® K1, the protected area in Biochip is a great environment for micro animals, not just bacteria. Micro animals feed on small particles such as fish waste, dead bacteria and algae. There are many different types of these micro animals, and they produce high levels of filtration. For example, Vortecilia filter 10,000 times their own volume per hour and feed on particles up to 5 microns in size. A hydrophilic layer in the Biochip creates extremely quiet zones in which micro animals can flourish, whereas other types of media would flush them out.
Add to existing K1 moving bed at a ratio of 1 part Biochip to 4 parts K1. Sold in 25-L (.9 cu.ft) bags.
