production decreases over time (i.e. more than a week with
regular feeding), first check the setting of the air valve flow
and then check the skimmer pump and air line intake for
clogging:
Turn off the skimmer pump at the power center.
Open the skimmer cover.
Disconnect the collection cup from the skimmer body.
Remove the mechanical filter materials on top of the
pump.
Slowly lift the skimmer body, removing it from the
chamber.
Gently pull the pump off the skimmer body and return the
skimmer to the chamber.
Open the impeller housing and check for calcium buildup,
damage to the impeller or the presence of foreign objects.
To clean the air line and air intake nipple, submerge the
inlet assembly with its air line in a bucket of hot water.
Clean the parts and reassemble the pump.
Reconnect the pump to the skimmer and slide the
skimmer back into the chamber as before. Keep the air
line out of the water.
Turn on the skimmer at the power center.
Gauge the air suction and the water/air mixture. If it still
seems inadequate, check again for blockage and repeat
steps 1-11.
Clean the collection cup and reconnect it to the skimmer.
Replace the filters atop the pump, keeping the air line out.
Close the skimmer cover.
Water level
Estimate the evaporation rate. Avoid water level drops of
more than 3 cm (1.2"): this much evaporation dramatically
raises salinity. Use RO water to replenish the evaporated
water and test with a hydrometer.
Water temperature control
Monitor the temperature at least twice/day, looking for
dramatic fluctuations. Avoid temperature differences of more
than 2°C during the day. During season changes and when
heating or cooling the house, monitor the tank temperature
more frequently, adjusting the heater as necessary. Red Sea
MAX's climate control system works best to keep the water
temperature at 24-27°C (76-83°F) in a room of a stable 24°C
(76°F) or cooler.
If the water temperature falls below 24°C (76°F)
Lift the skimmer cover and gently lift the heater enough to
see its operation light.
Turn the thermostat control knob to raise the temperature
by 2°.
One hour later, test the temperature again. Never change
the temperature by more than 2° at a time.
