The Evolution Aqua K+ Advanced Pressure Filter media is designed to
allow the unrestricted flow of water through the unit. This helps lower
the wattage of pump that can be used. Altogether, the K+ Micro Bead
filters offer excellent mechanical filtration and tremendous biological
performance. Features a clear 10" viewing dome for easy inspection.
Rather
than using conventional beads as its principle filter media, it uses
the K+ media. It provides a better biological and mechanical filtration.
This is because the K+ media has a vast surface area of 290 sq.ft. per
cu.ft. 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, preventing
ammonia and nitrite spikes after maintenance.
Water is pumped
into the filter from the pond, through a multi-port valve, this is 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 K+
filter media. The K+ media (which provides housing for 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. It is easy to clean. Simply
moving the handle on the multi-port valve into the corresponding
positions to perform a backwash and rinse of the K+ media.
Note: Blowers need to be protected from the elements. Place something over the blower so rain cannot get into the blower until it is time to backwash. If there is a ball valve, then you can store the blower inside until needed to backwash.
