NEXUS CLEANING INSTRUCTIONS - PUMP FED
CLEANING YOUR NEXUS PUMP FED
The central ‘Eazy’ section of the Nexus will collect all the debris and suspended solids that come
into the lter. In time you will nd out how often you need to clean this, and probably get into
a routine to keep the lter 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?. The indication that your
lter requires cleaning is when you see water
owing out of the overow as in Fig 3.2.
Normally we would not recommend leaving
the lter uncleaned more then 3 weeks. The
lter can be left longer if absolutely necessary
but this would not be best practice.
Cleaning procedure
1. Close the valve at the Nexus inlet and immediately switch off your pump.
2. Close the inlet to the inner chamber by inserting inlet slide-plate supplied with your
Nexus. Your Eazy is now isolated from the rest of the system
3. Turn the air valve to divert the air into the Eazy, close the air valve to the
bio stage.
4. The K1 media in the Eazy will now be agitated vigorously, or ‘boil’. As this happens,
all the debris trapped in the K1 will be released into the vortex area of the
central chamber.
5. After about 5 minutes, open the waste valve, allowing the waste to drain out
with the water Fig 3.3.
6. Take out the inlet slide plate.
7. Open the valve on the inlet, switch on your circulating pump.
8. Close the waste valve.
9. Close the air valve, to the inner chamber and open the air valve to the
outer chamber.
10. We would recommend that you perform the cleaning process twice wherever
possible to ensure best results.
