Protein skimmer
Check the foam production in the collection cup and reposition the Skim
Adjuster or air flow as required to maintain a stable dry foam. Empty and
clean the neck of the collection cup as required.
Pumps
Check that the circulation pump is working well and pointed in the right
direction. If you notice any regression in currents, check the pump and
the outlet nozzle for any obstructions (snails, crabs, carbon chips, etc.).
To ensure proper function of skimmer and circulation pump they should
be cleaned on a regular basis.
NOTE: Aquariums with higher levels of Calcium and Alkalinity will
require more frequent maintenance.
To clean the pumps:
• Switch the pump off at the Switch Box and disconnect the cable. and
remove it from the aquarium.
• Remove the impeller housing and take out the impeller.
• Clean all of the parts, impeller housing, impeller and the impeller
chamber of the motor by wiping with a soft cloth or brush. To remove
calcium carbonate deposits soak the parts in a weak acidic solution
(vinegar, citric acid) until deposits have dissolved.
• Rinse all parts thoroughly, reassemble the pump, ensuring that all
pipes are connected securely and return to the aquarium before
reconnecting the power cable to the electric supply.
NOTE: If the pump makes mechanical noise after cleaning, replace
the impeller. The impeller is a wear item and may need to be
replaced periodically.
Water temperature control
For optimum conditions a reef aquarium should be maintained at a stable
water temperature in the range of 24-28°C / 76-82°F (the stability of
the temperature being more important than the exact value). Slightly
higher temperatures can be tolerated for short periods of time as long
as the change in temperature is steady and not sudden. Monitor the
temperature at least twice a day, looking for dramatic fluctuations.
Avoid temperature differences of more than 2°C / 7°F during the day.
During season changes and when heating or cooling the house, monitor
the tank temperature more frequently.
Change the carbon filter
Replace the active carbon filter every two months.
