CLEANING YOUR NEXUS 220 PUMP FED
The central Eazy section of the Nexus will collect all the debris and suspended solids that
come into the filter. In time you will find out how often you need to clean this, and probably
get into a routine to keep the filter working at its optimum. Each pond is different, and the
regularity of cleaning is affected by stocking levels and feeding rates along with other factors
such as algae in the pond.
WHEN TO CLEAN?
We recommend cleaning the Eazy every 1 to 2 weeks. If however during this time
water is flowing out of the overflow as shown in Figure 9.2 then the Eazy is blocked
and requires cleaning.
Normally we would not recommend leaving the filter uncleaned more than 3 weeks.
The filter can be left longer if absolutely necessary but this would not be best practice.
OPERATING YOUR NEXUS 220 PUMP FED
Once your Nexus is installed and plumbed in as instructed, you are ready to fill the Nexus
and begin filtering your pond water.
To fill your Nexus first you need to open the inlet valve. With a pump fed unit you then
need to switch on your pump.
Once the Nexus is full, you will notice that both the K1 Media in the outer chamber and
the K1 Micro in the Eazy will float on the surface of the water. In a pond containing fish,
the media will absorb pond water and become semi-buoyant within a week.
This is perfectly normal.
Now your Nexus is full it is time to turn on your air pump to circulate the media making
sure the air valve to the outer chamber is open and the valve to the Eazy is closed.
