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.
