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