How Do I Clean My Nexus?

Below you will find the instructions for cleaning your Nexus 220 and 320+

1. To begin with, turn the pump off that is feeding your filter/pond.
2. Isolate the filter by closing any valves to stop water moving in or out of the filter.
3. Insert the cleaning pipe into the centre of the Nexus, stopping water moving between the inner and outer chamber.
4. Turn on the valve directing air to the inner chamber cage, which will agitate the water creating turbulence in the K1 micro media cage- this will dislodge any solid waste held by the K1 micro into the inner chamber. This needs to be done for several minutes to properly cleanse the K1 of fish waste.
5. Once the K1 micro has been bubbling for several minutes, it is time to open the waste valve for the inner chamber. This will send all of the soiled water and solid particles out of the Nexus to waste.
6. Once the inner chamber has emptied, close the waste valve and switch the air valve back to the Nexus outer chamber.
7. Refill the inner chamber of the Nexus by opening the relevant valves, connecting the filter to the pond and removing the Nexus cleaning pipe, allowing water to circulate between the inner and outer chamber once again.
8. Turn the pump back on, recirculating water between the pond and filter.
9. Top up the filter/pond to the required level.
