TROUBLESHOOTING

Green water

Settlement test the water to ensure that there is no sediment suspended in the water. It there is 

follow the brown cloudy water trouble shooting guide.

At dusk check that the UVC light is illuminated by holding a piece of paper up to the UVC outlet 

and looking for the reflected pale blue UVC light. Turning the lamp on and off may aid visual 

identification. (Ensure the UVC lamp is not more than 6 months old).

The UVC may be working effectively but the foams are too clean and are unable to remove the fine 

coagulated waste. Treat the pond with Interpet Clear Pond and do not clean the foams until the foam 

chamber starts to overflow into the carbon wool chamber.

The flow rate of the pump exceeds the maximum flow rate that the UVC is able to handle. Check the 

filter specification chart and reduce the pump flow rate if needed. It is possible to purchase a optional 

flow control valve that may be fitted inline between the pump and the filter to control the flow rate.

The filter is too small for the pond, check the filter selection chart.

The UVC quartz sleeve is dirty or coated in lime scale. Gently remove the quartz sleeve and clean in 

Blagdon pond pump cleaner.

Follow all cloudy water trouble shooting points.

UVC light not illuminated

Check all fuses / RCD and electrical connections follow electrical installation (pages 7-8).

Poor flow into the filter or out of the filter

Inspect and clean your pond pump, check that it is in good working order.

Check foams and filter pads ,clean as per routine maintenance if blocked.

Always use the minimum length of inlet or outlet hose needed as this will reduce back pressure due 

to friction.

Ensure that the inlet hose connecter has been cut correctly to size, if not this will restrict the flow 

from the pump into the filter see diagram page 5.

Ensure that the correct number of outlets are being used (see page 3).

Ensure that the inlet hose is not kinked or crushed.

Ensure that the outlet hoses are under 1m in length and that there is a drop of 15cm over this distance, 

ensure that they are not kinked crushed or have a sharp bend as this will stop the filter draining correctly.
