THE NEW NEXUS EAZY 320 from EVOLUTION AQUA! Nexus 220 and 320 Introducing the next generation of
Nexus Filtration Systems from Evolution Aqua.
The Nexus 320 and 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 and 320 feature 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 work 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). Key Features and Benefits Improved Mechanical Filtration The new design of the Eazy enables the Nexus to capture
solids more effectively than before. K1 Micro is used inside the re-designed
Eazy helping to deliver improved capture of fine particles, delivering
unrivalled mechanical filtration. Improved Flow The new Eazy features an improved pattern of slots in the
stainless steel body which makes the filter more efficient. Water can pass
through the Eazy through all sides and from below, much more effectively than
before. This feature combined with the use of K1 Micro makes for improved flow
rates through the entire mechanical filter stage. Dramatically
Improved Clarity The Nexus 320 and 220 filter systems use two types of filter
media to deliver optimum levels of clarity in your pond. K1 Micro is used in
the Eazy to improve mechanical filtration while the tried and tested K1 Media
is used in the moving bed outer chamber, delivering the biological filtration. Easy To
Clean And Maintain A key feature of all Nexus filtration systems is the sheer
ease of maintenance. This still remains the case with the new Nexus 220 and 320
systems. The Eazy is simply cleaned by using a combination of the cleaning
pipe, air valves and ball valves fitted to the Nexus, meaning you don’t need to
get your hands dirty. The clear lid fitted to the Eazy also makes it easy to
visual inspect the K1 Micro media. Better Solids
Handling Inside the centre mechanical stage of the Nexus, there is a
much larger area for solid waste to be captured and to settle. This area can
then be cleaned even easier than before ensuring the filter does not clog up
with unnecessary amounts of waste. Removable
Eazy All Eazy filters used in the Nexus 320 / 220 series can be
removed if needed with the K1 Micro in place. This added feature is ideal when
undertaking further maintenance. How The Nexus Works The Nexus filter is simple yet innovative. Water enters the
Nexus via the inlet into the inner chamber which works as a basic vortex
allowing larger solids to settle out. The water then passes through the Eazy
where the finer particles are removed at the mechanical stage of filtration.
From the Eazy the water passes into the outer chamber where the biological
stage of filtration takes place. An air pump is used to constantly aerate the
K1 Media in the outer chamber ensuring the moving bed delivers fantastic
results. Water then passes through the grill into the Exit Chamber,
where it is returned to the pond through the outlet. 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 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 your filter’s biological capability 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. Specifications
