If the skimmer is used with new water on an aquarium it is common to find an excessive
quantity of small bubbles and often the skimmer cup fills with a clear liquid. This is due to
the high surface tension of the new water which prevents the bubbles from bursting. Once
the water matures this effect will go away but can take up to 2-3 weeks. The effect is
different on different salt brands and is often dependant on levels of conditioning agents
added to the salt. Once these are skimmed out, then the skimmer will act normally.
Heavier feeding in the initial stages will give the chemically pure water something to react
with and allow it to mature into proper aquarium salt water rather than the initial chemical
soup which is new salt water.

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. 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 venturi tube.
