WARNING:
Disconnect electrical supply
before commencing any work on the filter.
1. FLOW COMING OUT OF THE FILTER IS
SLOWING DOWN.
The filter sponges are blocked and require
cleaning. Perform a back wash on a regular
basis, this will ensure you filter is performing to
its full potential. (See Backwashing Your Filter)
In extreme cases the filter media may be
severely blocked. Dissemble the unit and clean
the media. (See Setting Up Your Filter)
Check pipes for restrictions, blockages or
breaks. Pipes that are buried under the ground
could be crushed by rocks or the weight of soil
on top of them, especially possible after
prolonged periods of rainfall.
The intake to the pump in the pond could be
blocked by leaves and debris. If the flow into the
filter is restricted then this will mean less flow
coming out.
2. THE PUMP FLOW RATE IS FINE UNTIL I
CONNECT THE FILTER THEN IT
DECREASES CONSIDERABLY
All pressurised filters will cause a frictional
resistance in the pipe work. This means by
there nature they will reduce the output of the
pump. Depending on the size of the pump and
pressure (Head Max) of the pump this could be
up to a 50% reduction.
Try moving the pump closer to the inlet of the
filter or raising the pump off the bottom of the
pond to again bring it closer to the inlet.
The size of the hose used may also affect the
flow of water through the filter. Use the largest
hose size possible and remove the smaller size
on the hose tails as they will restrict the flow
considerably.
3. MY POND WAS CLEAR BUT NOW IT HAS
GONE GREEN AND CLOUDY (UV Models
Only)
Check the ultraviolet (UV) globe is still
functioning. All globes should be replaced after
10,000 hours (12 months) maximum but they
do loose effectiveness from the day they are
first used.
Trouble Shooting
The quartz sleeve which protects the UV globe
may require cleaning, see Replacing/Cleaning
UV-C for instruction on how to remove the
quartz sleeve.
Check pH and hardness levels of your pond
water, a filter can not perform correctly if the
hardness is too low.
4. MY FILTER IS LEAKING
Check all restrictions as above. Normally leaks
will occur when the water is not able to pass
through the unit fast enough.
Check and replace foams. Foam structure
breaks down over a period of time and normally
they will need to be replaced once a year. When
they break down the pond water can not pass
through fast enough.
Check the O-ring which seals the lid to the
canister and the O-ring which seals the quartz
sleeve on the UV-C. They will deteriorate and
require replacing periodically. Any time the unit
is disassembled lubricate them using a pond
safe lubricant.
Check the hose tails and hose clamps are tight
and that the clamping ring is on and closed
correctly.
Ensure the cleaning controller is switched to
filtering mode.
5. SINCE FIRST INSTALLING MY CLARITEC
I HAVE NOT BEEN ABLE TO ACHIEVE
CLEAR WATER OR GOOD WATER QUALITY
It could be the filter is too small for the biological
loading being put upon it. This can be because
the pond is too large, too many fish or more
often the case over feeding of the fish which
leads to a lot of uneaten food sinking to the
bottom of the pond and decaying. Decaying
food and leaves etc, causes the filter to have to
work much harder. If the filter is only just big
enough for your pond size this can mean that it
can’t cope. Recommended action. Clean pond
and feed only what the fish consume in a few
minutes, thus reducing the biological load on
the filter and improving the all round health of
the pond. In essence a filter will help maintain a
clear healthy pond, it can not turn an extremely
dirty soiled pond in to a pristine one without a lot
of help from the pond owner.
