Nexus
The Nexus 220 filtration systems deliver dramatically improved
levels of clarity for ponds. Building on the success of the award winning Nexus
range this new generation of filters cleverly combine mechanical and biological
filtration into one advanced filter system, whilst being incredibly easy to
clean and simple to install.
The Nexus 220 features a re-designed Eazy filter which now
utilises the all new K1 Micro filter media, in a static bed, to deliver
improved levels of mechanical filtration. The Nexus filter systems also use the
acclaimed K1 Media in the moving bed to deliver outstanding levels of
biological filtration. Together this combination of filter media works to
deliver crystal clear and healthy water.
All Nexus filtration systems can be installed on pump fed or
gravity fed setups depending on your pond configuration. The Nexus 220 is
suitable for ponds up to 18,000 litres (4,000 gallons) while for larger ponds
the Nexus 320 can be installed on ponds up to 34,000 litres (7,500 gallons).

How the Nexus
works 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 at the mechanical stage of filtration, thanks to the static bed of
our award winning K1 Micro filter media. The mechanically clean
water then passes to the outside chamber of the nexus where the K1 Media
moving bed is located for biological treatment prior to being returned 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 piece of the K1 Media. These
bacteria convert Ammonia and Nitrite into harmless Nitrate. Water then passes through
the exit grill into the outlet, returning back to the pond. |

The Eazy Filter
The Eazy is a stainless steel vessel containing a set volume of K1 Micro
Media (20 litres in the Nexus 320 and 18 litres in the Nexus 220) which is
located within the inner chamber of the Nexus. After water enters the Nexus it
rotates around the Eazy in the inner chamber with a downward motion allowing
the larger solids to settle to the bottom of the chamber before passing through
the slots of the Eazy into the static K1 Micro. The water flows from all angles
through the K1 Micro where improved mechanical filtration and settlement takes
place and fine particles are caught within the K1 Micro. The water then flows
through the slots in the centre column and into the outer chamber.
Biological Filtration - K1 Moving Bed
The outer chamber of the Nexus contains the moving bed of K1 Media. 100
litres of K1 Media is supplied with the Nexus 320 with the option to add an
extra 200 litres of K1 Media should it be needed. The Nexus 220 is supplied
with 50 litres of K1 Media, with the option to add an extra 100 litres of K1
Media if needed. This allows the biological capability of your filter to grow
with your fish.
The outer chamber is where the final stage of biological treatment
occurs. Biological breakdown occurs through different strains of bacteria
living on the protected surface area on each piece of the K1 Media. These
bacteria convert Ammonia and Nitrite into harmless Nitrate. The amount of
Ammonia and Nitrite produced in the pond is dependent on feed rates and the
type of food used. For higher feed rates additional K1 Media should be added
into the outer chamber.
