Troubleshooting - Sera Marin Precision Biotop LED Cube 130 Instructions For Installation And Use Manual

One day after starting the unit you should adjust it more
precisely for the first time, in case too much liquid is
skimmed as well as in case no foam has formed: If no
foam has appeared so far, the skimmer should be im-
mersed deeper. The air supply should not be reduced at
all if possible. If the flotate is too watery, the skimmer
should be placed in a higher position by re-adjusting the
holder bracket. Also, the outlet valve should be opened
further in this case.
Cleaning
Pull mains plug before cleaning.
The flotate cup (5.2) with the integrated sieve must be
cleaned regularly. Adhering fat remainders from the flotate
would make newly formed foam burst quickly. Therefore,
the flotate cup must be taken out of the main pipe and
cleaned under running tap water without using deter-
gents at least twice per week. Then the flotate cup is
pushed back into the main tube up to the snap-in points.
Deposits may form on the bottom of the skimmer over
time, which reduce outflow at the bottom and thus affect
the skimmer performance. Therefore, the entire skimmer
should be cleaned regularly.
You can remove the bottom part with slits (5.7) from the
pump and clean it without using detergents. When look-
ing into the pump part from underneath you will see the
round intake opening of the pump (5.15) directly beside
the pump body. It must always be clean and never
clogged.
The internal pipe can be removed after having taken off the
flotate cup. The main pipe is glued to the motor part and
cannot be removed.
The ceramic shaft must first be drawn out of the motor
part from the bottom side before the rotor is taken out as
to prevent breaking it.

Troubleshooting

:
Problem
Insufficient air intake rate
Foam too moist/too much foam
Foam too dry/very viscous foam
Insufficient foam formation
Foam formation too strong, very
brownish flotate, very sticky foam
Foam formation breaks down
The internal pipe (5.3) accessible. This part can also be
pulled off in an upwards direction, allowing to take the ro-
tor (5.6) of the pump out and clean it. Lime may deposit in
the intake connector (5.8) where air is drawn in, and ob-
struct the air supply. You can drip sera pH-minus direct-
ly onto the lime deposits to remove them. This must be
done outside the aquarium.
SAFETY PRECAUTIONS:
• Always unplug all electrical accessories before any
kind of work is carried out in the aquarium!
• The power cord of the pump must not be repaired or
replaced! If the power cord is damaged, the entire unit
must be replaced or disposed.
• The maximum temperature of the water must not ex-
ceed 35°C (95°F).
• The pump performance will considerably increase in
case the air supply is suddenly switched off, the skim-
mer can overflow, and large amounts of water may be
pumped from the tank!
• Before using the unit, please make sure that frequency
and voltage of the mains supply comply with the fre-
quency and voltage indicated on the type plate.
• Do not lift or carry electric devices by the mains cord.
• Operate the unit only with a connected circuit breaker
(RCD / FI ground fault interrupter, 30 mA).
• Use this unit only for the described purpose.
The sera marin Protein Skimmer PS 200 is an open flow
unit. The unit cannot work, and the oxygen supply of the
aquarium will be strongly inhibited, if the outlet into the
aquarium is clogged or otherwise obstructed.
Possible cause
Intake valve (5.12) insufficiently opened
Air hose (5.11) is encrusted with lime or dirty
Intake nozzle (5.8) on the pump is dirty
Pump performance is too low
Water level within the unit is too high
Water level within the unit is too low
Insufficient pump performance
Insufficient amount of air
Water strongly polluted
see: Insufficient foam formation
Feeding fatty food (fish, mussels)
Air intake congested

Possible solution
Open intake valve (5.12) further
Clean
Clean
Clean rotor and shaft
Place skimmer in a higher position
Immerse skimmer deeper
Clean rotor, shaft and intake nozzle
Open intake valve (5.12) further
Partial water change, feed less
Increase flotate moisture
Foam formation will begin again after a
few hours
Clean air intake or open further
