Lighting
The LED modules have a built-in Wi-Fi network and must be connected to a smartphone or Wi-Fi enabled computer to get
the benefits of all of the features. To set up and program the LED's follow the instructions provided with the LED modules.
Programming guidelines:
Photoperiod: Day/moonlight
The day photoperiod should be between 8 – 12 hours with no more than 4 hours at maximum intensity and at ramp
up/down rate of approximately 25% (of maximum intensity) per hour. Corals and fish must have daily periods of
darkness. LED moonlight should be limited to 1% of the maximum light intensity for a maximum period of 6 hours.
Acclimation
To prevent photo-inhibition due to the high intensity of LED lights, an acclimation period is recommended for new
systems or when introducing new corals.
Acclimation will vary for different kinds of corals however it recommended to allow a period of 8 weeks for new set-ups
as follows:
Set the day photoperiod as described above however the 4 hour peak intensity to should not exceed 60% of maximum.
Increase the peak intensity by 10% every 2 week.
During the acclimation period look for signs of photo stress and photo-inhibition such as:
• Whitening/Bleaching of the upper section of the tissue (the lower section will continue to show pigments and
zooxanthellae).
• Polyps retraction.
• Gas bubbles inside the soft tissue.
In the event of any of the above symptoms immediately reduce the peak intensity by 20% for about 4 weeks and
thereafter increase by 5% per week until maximum intensity is reached.
When introducing new corals to already acclimated systems, start by positioning them at the lower levels of the
aquarium and gradually raising them to their desired position over a period of several weeks. Keep watching for signs of
photo inhibition/stress and if necessary return an affected coral to lower levels for recuperation.
NOTE: Red and Green wavelengths are not recommended for use in Reef systems as they may promote the
outbreak of unwanted Algae or Cyanobacteria.
WARNING: The LED module is not waterproof. Do not get the unit wet and do not submerge any part of it or the
power cord in the aquarium water.
WARNING: LED lights produce extremely intense light output that may damage or injure your eyes.
Do not look directly into the LED's any time the fixture is illuminated.
