Internal Protein Skimmer MC 501
The Deltec MC 501 is a Multi Compact high performance dual purpose skimmer for
use inside the tank or fitted within a sump.
Installation inside the aquarium
The skimmer is supplied with an adjustable bracket which can be fitted to the right
or left hand side of the unit and allows the height of the skimmer to be set above
the water level. The skimmer housing must extend by a minimum of 80mm above
the water line as illustrated on the diagram. The bracket allows the unit to hang
from the edge of the aquarium and is secured to the skimmer body with 2 screws. If
the skimmer does not hang vertically within the tank, adjust screw accordingly until
this is achieved.
Installation inside a sump
The skimmer can be hung on the side of the sump as described above or can be free
standing. Ensure that the water intake and outlet are unobstructed. The minimum
depth that the unit should be immersed for satisfactory performance is 120mm. In a
sump, correct setting of the weir plate is important and the air should be closed a
little to the 2 o'clock position.
Operation
After the skimmer is installed and the height adjustment water level is correct, the
fine adjustment is done by raising or lowering the skimmer cup. Allow app. 24 hours
before doing so.
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. The
MC 500 is fitted with a Aqua Bee pump. Aqua Bee pumps are fitted with a little flap
inside the outlet of the pump, which flips 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 3 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. Make sure that the impeller rotates freely on
the ceramic shaft. If not submerge in lime scale remover.
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.
