The Nexus Eazy Water Polisher and Air Backwash Kit basically consists of two elements to add additional functionality to your NeXus 200 and 300 models.

The first improvement is achieved by adding a full height metal plate, instead of the half height metal plate in your existing filter, immediately followed by a plastic weir. This new design utilises the whole of the static K1 which maximises the cleaning potential of the filter.

Equally, the second improvement is achieved by adding the air backwash kit, using the supplied parts, the air line fits into the 'D' shaped exit grill, the other end is connected to the air supply for the biological stage using the supplied valve.

Cleaning is simple and effective and the subsequent results are reported to be quite outstanding.
