Pond Filtration Systems » Nexus

The Nexus Eazy is Evolution Aqua's exciting new filter system. It incorporates the industry proven Kaldnes Moving Bed technology coupled with the innovative Eazy mechanical filter.

Combined, they provide outstanding water clarity and quality, pump or gravity fed. Extremely easy to clean and maintain, with minimal running costs, the Nexus Eazy system is designed and built to last a lifetime.

How the Eazy works - The Kaldnes is retained in a stainless steel basket and has been proven to trap incredibly small particles of waste. Cleaning the Kaldnes is a simple matter of turning on the air tap to the settlement area thus agitating it and causing the waste matter to be dislodged from the media so it can be drained to waste.

Nexus Eazy systems are complete units and include the Nexus body, Eazy central vortex, air backwash line, air diverter valve, unionized ball valves to waste, and Kaldnes media for both the Eazy (static Kaldnes) and the bio-reactor (fluidized Kaldnes).

The Nexus 200 Eazy and Nexus 300 Eazy are the same system in 2 sizes for different pond volumes.

• Nexus 200 Eazy, 2640 gph max flow, for ponds up to 4700 gallons.
• Nexus 300 Eazy, 3960 gph max flow, for ponds up to 8900 gallons.

Upgrade your existing central sponge block to the new Nexus Eazy. The Eazy features Evolution Aqua's new solids removal system utilising static Kaldnes. The Kaldnes is retained in a 316 stainless steel enclosure and has been proven to trap incredibly small waste particles, without disrupting flow through the system. Cleaning the Kaldnes is a simple matter of turning on the air tap to the settlement area, thus agitating the static Kaldnes. Waste is then dislodged from the media, and purged through the central vortex drain.

The Nexus Eazy 200 retro kit inlcudes all the necessary parts, plus 35 litres of Kaldnes media, to upgrade your exisiting sponge based Nexus.

The Nexus Eazy 300 retro kit inlcudes all the necessary parts, plus 45 litres of Kaldnes media, to upgrade your exisiting sponge based Nexus.

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.

Increase the bio-capacity of your Nexus system by simply adding more Kaldnes media.? Kaldnes Moving Bed process creates an oxygen rich environment, with an even distribution of water throughout the media, thus avoiding dead areas normally associated with static type media.? Totally maintenance free and self cleaning.? Sold in 50 litre bags.

For exposed installations, cover your Nexus with a custom fit lid.
