The brand new K1 Micro Bead filter is a game-changing filtration system that completely re-invents the bead filter. It is designed to allow the unrestricted flow of water through the unit, meaning that a lower wattage pump can be used, which can save you money. Altogether, the K1 Micro Bead filters offer excellent mechanical filtration and tremendous biological performance.

K1 Micro Biological Media
Rather than using conventional beads as its principle filter media, it uses K1 Micro media. This provides better biological and mechanical filtration, since the K1 media has a vast surface area of 950m2 per m3. This protected surface area safely houses beneficial bacteria and prevents them from being flushed to waste during the cleaning cycle. Only dead bacteria and waste debris will be discharged. This prevents ammonia and nitrite spikes after maintenance.

How the K1 Micro Bead Filter Works
Water is pumped into the filter from the pond, through a multi-port valve where the internal pipework directs the water to the bottom of the unit. As the water flows upward, dirt and debris is trapped within the mass of K1 Micro filter media. The K1 Micro media (which provides a beneficial bacteria) delivers biological filtration. The filtered water flow back into the pipework at the top of the unit, through the multi-port valve and back down the return line into the pond. The filter is incredibly easy to clean, by simply moving the handle on the multi-port valve into the corresponding positions to perform a backwash and rinse of the K1 Micro media.
