Evolution Aqua Nexus Eazy
The launch of 2 new lines will dramatically improve the performance and ease of maintenance of all Nexus models. They are the new Nexus Eazy and the Nexus 2000/3000 range.What this means is that whether pump or gravity fed, using an Answer or not, we now have more efficient and more user friendly solutions for everyone.
We have worked tirelessly to replace the central foam that was an excellent polisher, but it was after all, 'a foam' and needed maintenance. In some conditions of heavy fouling, 
it was difficult to clean.We have been developing an exciting and effective product called the Eazy. I know you will be amazed at its performance, design, build quality, price and the clean water it delivers. It is extremely 'eazy' and "clean" to maintain, has minimal running costs, is designed and built to last for life. Great news, available as retro fit for existing customers.
By using all of Evolution Aqua's knowledge and experience in product design and development as well as manufacturing and engineering, the Nexus Filtration System revolutionises the way ponds are filtered. The Nexus is a cleverly combined mechanical and biological filter creating an effective, high performance filtration system delivering superb water quality and clarity for ponds from 4,500 to 34,000 litres*.

Kaldnes K1
K1 fluid bed media has a surface area of 800sqm per cubic metre.Fluidized by air providing maximum effective removal of ammonia nitrite.Use approx 30% of chamber capacity. Kaldnes Moving Bed™ process, which has been scientifically tried and tested in fish farming and waste water treatment for over 10 years, is now by Evolution Aqua.
How it works...
The Eazy is a stainless steel vessel containing a volume of static K1 media which is located within the centre chamber of the Nexus.Water enters the centre chamber and then enters the Eazy via slots in the lower half of the unit. This results in a downward flow causing many of the larger solids to settle out prior to entering the Eazy.
The size of the slots will not allow large mechanical waste to enter the cylinder thus acting as a first stage mechanical filtration. The water then passes through the static K1 media utilising up and side flow and this process causes the fine solids to become entrapped.The mechanically clean water then passes to the outside chamber of the Nexus where the Kaldnes moving bed™ is located for biological treatment prior to being returned to the pond.
Maintenance
The Nexus Eazy is extremely 'eazy' and pleasurable to clean.The water pump is switched off and an air valve is operated which diverts air from the main Nexus air ring into the base of the Eazy.This causes the K1 media to be agitated and cleaned vigorously.As this happens the captured particles are flushed out into the central chamber of the Nexus, allowing you to see the amount of waste that has been filtered out. Once the K1 media has been agitated for a sufficient period, the water in the central chamber is flushed to waste using the purge valve provided at the base of the Nexus. Once clean, the air flow is re-directed back to the main air ring and the system started again.The whole process from start to finish can take less than two minutes. No high pressure pumps are needed unlike pressurised systems, there are no running costs and the media can be visually checked that it is 100% clean after a maintenance cycle, unlike closed systems. Its simple,clean,'eazy' to do and actually enjoyable!
