Filter Leaks
•
Check that the filter outlet nut and O ring have been correctly assembled and that they are hand tight.
•
Check the hosetail connecter O ring seal is fitted and aligned correctly on the end of the hosetail
fitting and that the inlet cover is hand tight.
•
PTFE tape may be needed to give a water tight seal and should be applied to the inlet or outlet
hosetails.
•
Always secure the filter inlet hose and outlet hose with a jubilee clip.
•
Insure that the filter is installed on a flat and level base.
Cloudy/Brown Water
•
The flow rate / pond turnover is to high or to low. Check that you have correctly calculated the
pond volume and that pump flow rate is within limits. (see connecting your pump page 6)
•
The filter is not being supplied with water 24 hours a day. Do not turn off your pump or UVC.
Continuous running is needed to maintain a clean and healthy pond.
•
The filter foam pads are insufficiently blocked to trap the fine waste. Treat with Blagdon Clear
Pond treatment.
•
Do not clean the foams until the filter foam chamber starts to overflow into the carbon wool
chamber.
•
The water is extremely dirty, remove pond waste and leaves - carry out a partial water change.
•
Filter is incorrectly sized - refer to filter performance and specification chart. Calculate the pond
volume - see connecting to your pump page 6.
•
The filter foams have not been positioned or replaced correctly,ensure that the foams fit tightly
within the filter chamber.
TROUBLESHOOTING
In order to correctly identify if you have green water or cloudy/brown water, a settlement test
should be carried out.
Take a glass of pond water and allow to settle for a few hours. When the glass is stirred a small
layer of settled waste can be seen at the base of the glass. This indicates that you have brown
or cloudy water and that if you have a UVC model it is working correctly. If there is no settlement
it indicates that you have green water and the UVC is not working correctly.
