K+ Pressure Filters (previously K1 Microbead Filter)

K+ Pressure Filters (previously K1 Microbead Filter)



Water is pumped into the filter from the pond through the multi-port valve where the internal pipework directs the water to the bottom of the unit. As the water flows upwards inside the K+ Pressure Filter, dirt, debris and waste are trapped within the mass of K+ filter media. The vast protected surface area provided by K+ Media also provides a home for the beneficial bacteria, along with filter feeders such as Vorticella and Rotifiers delivering mechanical and biological filtration.


The filtered water flows 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 K+ Pressure 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 a rinse of the K+ media.
