The world famous Nexus pond filter from Evolution Aqua. With proven Kaldnes Moving Bed™ biological filtration combined with the Eazy™ static Kaldnes fines filtration, the most popular system in the world is now better than ever. Combined, this revolutionary system provides outstanding water clarity and quality, in either pump or gravity fed configurations.
The Nexus Eazy system provides zero maintenance within the fluidized biological stage, low operating costs (no need for a pressure pump), and best of all the system delivers both mechanical and biological stages in one unit. Extremely easy to install, clean, and maintain, the Nexus Eazy system is designed and built to last a lifetime.
How the Eazy works – Water enters the central vortex, where heavy solids simply settle to the bottom of the vortex. Water then travels through static Kaldnes, which is retained in a stainless steel basket. This process and has been proven to trap incredibly small particles of waste. To clean the Eazy, simply turn on the air tap to the settlement area to agitate the media, and then open the drain to the central vortex.
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).
After the wastes have been removed in the central vortex, the water then enters the biological stage, which consists of the Kaldens Moving Bed process. An air ring at the base of the outer bio-chamber releases air continuously to rotate the Kaldnes media, thus providing the best possible environment for bacteria to colonize, and an optimized environment for your koi.
Kaldnes has been proven to be many time more efficient than static media types. Incorporating fluidized Kaldnes into the product range is a major breakthrough in performance. The Kaldnes Moving Bed process is exclusive to Evolution Aqua and is included in the Nexus.
The Nexus 210 Eazy and Nexus 310 Eazy are the same system in 2 sizes for different pond volumes.
Nexus 310 and 210... New Features;
The Nexus filtration System has proved itself to be the most successful Koi Filter in the World. Innovative design and the use of cutting edge technology has produced a product that is proudly used by Koi keepers the world over. Now the Nexus has just got even better!
The Nexus 310 and 210 incorporate new features, designed to make Nexus even more efficient at waste removal, even easier to clean, and even more convenient to use.
The All New Eazy – that is the solids removal chamber, has been redesigned from the bottom up. It is bigger, allowing for better flow of water through the static K1. This means that the Nexus removes more of the suspended solids, and is even better at producing the clarity demanded by the koi keeper! The one way valve that is now attached to the outlet of the Eazy, has made cleaning easier. The improved water flow also means more efficient cleaning of the Static K1. The Eazy is now covered by a clear lid, this ensures that the precise amount of K1 media is always present with the Eazy chamber, and none can escape.
In pump fed operation, the Nexus has an Overflow and in gravity fed operation, a Bypass, which mean that if you need to leave the filter for longer than you normally would in between cleaning then the water can now bypass or overflow out of the filter and back into your pond. The filter will continue to work as normal, but the excess water will bypass/overflow back into the pond.
