Nexus Filters and Retro Kits

Bring your existing gravity fed Nexus/Answer combination up to current specifications by retrofitting the new EA fines polisher and air backwash kit. This retro kit installs in the current outlet port of the Nexus. After passing through the fluidized section of the Nexus, water then transfers through the full metal plate rising over a weir plate into a fine polisher which contains static Kaldnes media, therby trapping any remaining fine solids. This retro kit dramitically improves water clarity. Cleaning the static Kaldnes is a simple matter of diverting air from the bio-stage using the included valve to agitate the media, then purging this waste as normal.

Kit includes all fittings and hardware necessary to convert your Nexus/Answer combination.

Note: For use only in gravity fed configurations.
