Designed by Aqua Ultraviolet
This is the next generation of filters and one of the best tools for Koi ponds. The Ultima II is specifically engineered to meet the environmental demands of koi ponds.The lightweight media is designed for very high flow rates. There is a patent pending on this tubular media which has low head loss and a very high biofilm surface. The "Y" shape on the inside and wings on the outside affords a protective surface under back washing and our patent pending backwash system will keep the media from clogging. The same properties have been added to this media in three different sizes with random lengths and diameters to avoid stacking. One cubic foot of Ultima II biological filter media is equal to 750 square feet of surface area. Cleaning the filter is done by internal jets.

Advanced filtration systems for Koi ponds now with NEW K+ Media
Building on the tried and tested technology that has been present in the world renowned Nexus, the team at Evolution Aqua have gone even further to enhance their number one koi pond filter.
The Nexus 220+ and Nexus 320+ filters now come with a new filter media called K+ Media in the moving bed outer chamber for vastly improved biological filtration and faster filter maturation. The new Nexus+ filters are now supplied "auto ready", with factory fitted fixings already in place, making it even easier to upgrade to the Nexus Automatic Cleaning System.
Water from the pond enters the nexus via the inlet into the inner chamber which works as a vortex, allowing larger solids to settle out. Water then passes through the grills in the stainless steel “Eazy” filter, where the finer particles are removed by the static bed K1 Micro® filter media. The clean water then passes to the outside chamber of the Nexus for biological treatment before returning to the pond. At this stage, biological breakdown occurs through different strains of bacteria and filter feeders living on the protected surface area of each K1+ Media filer. The bacteria convert Ammonia and Nitrite into less harmful Nitrate. Water then passes through the exit grill into the outlet and returns to the pond.

The EazyPod Automatic is a self-cleaning, mechanical and biological filter system for ponds up to 2,640 gallons.
The integrated control box contains an adjustable timer which initiates a cleaning cycle automatically - meaning your filter will clean itself even when you’re not there! Inside the control box, the electronic connector blocks control the automated waste valve, along with your choice of circulating pump (not supplied). It even houses an integral air pump which kicks in automatically to clean the K1 Micro media.
Crystal clear, healthy water is achieved by K1 Micro filter media, which also provides enhanced biological benefits by way of its protected surface area.
The Eazypod UV Automatic features an integrated 18 Watt UVC built in to the inlet section of the filter, helping to clear green water. Available in 2 models, users can select either the EazyPod Automatic or the EazyPod UV Automatic (with built-in 18 watt UV).
