UV OPEratiOn
the ultraKlean pond filter with uV prevents/eliminates
™
single celled algae commonly referred to as green water. the
ultraKlean pond filter includes a bulb saver timer feature
™
that extends the life of the uV bulb by allowing you to set
the operating time for the bulb based on the water quality
conditions in the pond.
• Setting the UV Timer – if the pond water has a planktonic
algae bloom (green water) then use the "select uV time"
button to set the uV timer to 24 hr setting (always on). in
general the cleaner and clearer the pond water, the less
the uV light needs to be operated. once the green water
is cleared you can reduce the uV timer to the 12 hr setting
(on for 12 hours/off for 12 hours) or possibly to lowest 6 hr
setting (on for 6 hours/off for 18 hours). if you notice the
green water beginning to reappear you can increase the
uV light operation time until the green water clears.
• Bulb Life – for effective clarification, the uV bulb should
be replaced after 12 months of continuous use, when
operated on the 24 hr setting. the bulb saver feature can
extend the life of the bulb to 2 years when operating on
the 12 hr setting or 4 years when operating on the 6 hr
setting. Please note even though the uV bulb still emits
light it may have lost its effectiveness at clarifying if the
recommended operating duration has been exceeded.
• Cleaning/Replacing the Quartz Tube – a dirty quartz
tube will reduce the effectiveness of the uV bulb. Debris
and mineral deposits can be cleaned using a mild acid
like white vinegar or a non-abrasive calcium, lime or rust
remover with a soft bristled brush or sponge.
