use different salt or feed heavily
for a period, empty skimmer cup

last for several weeks.
Pump does not start
Front bearing of the impeller stuck.
When the pump (after having been
used) has been stored dry for a period
of time, the front bearing can "dry out".
Remove impeller with the extractor tool
as illustrated and loosen the bearing by
moving the bearing plate around and
along the ceramic shaft in tap water.
Maintenance
The Deltec skimmer range should need very little adjustment and maintenance once set correctly however due to the
high levels of
calcium in marine aquariums it is common for deposits to build up on moving parts requiring periodical cleaning
. Deltec
pumps are
fitted with little flaps inside the outlet of the pump and inside the housing, which flip from one side to the other depending on the
direction of rotation thus ensuring that the pump always operates at full duty.
It is recommended every 6 months, or when required,
that the pumps are removed from the skimmer having first drained the body of
Water.
Check and clean the impellor of debris. Ensure that the direction flaps move easily and if necessary soak the neck of the pump
housing in white vinegar or lime scale remover to dissolve any calcium carbonate deposits.
A build up of calcium, dust and salt can
restrict or block the venturi inlet on the connecting pipe work and reduce the skimming
efficiency. This should be checked and
carefully cleaned with a toothpick or fine drill rotated between the fingertips.
It is advisable to stop the pump for approximately 15 minutes once every week in order to dissolve any dust or salt crystals that may
have collected in the venture tube.
