Pump does not start
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 . 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. If necessary soak 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.
Please observe: The water level adjuster must be checked at regular intervals (at least
once a week) for accumulation of dirt or other substances with may inhibit or interfere with
its proper function. If required please clean. For this purpose the water level adjuster can be
simply removed by pulling it upwards. After reinstallation of the water level adjuster please
make sure it is correctly set. Any foreign bodies, limestone build up ect. can cause the
skimmer water level to raise, in extreme cases the skimmer may get flooded.
