Moonlight plays an important role in the lives of aquatic creatures. Fish, invertebrates, and photosynthetic corals are all intimately bound to the natural lunar cycles. By recreating lunar luminescence in aquariums you may not only benefit the tanks inhabitants, but add aesthetic value to the aquarium. Our modular moonlights are a good addition to any aquarium, including reef, saltwater and freshwater systems. This system includes the Moon Controller, one Moontube Moonlight, 120VAC power supply, operating instructions, and mounting clips for the moonlight. We recommend one Moontube per 25-40 gallons of tank volume. For larger systems, additional Moontubes can be purchased separately. The Moon Controller is a micro-processer based digital dimmer and moon cycle timer. In moon cycle mode, the controller varies the intensity of the moonlight over a 29.5 day period to mimic the lunar cycle. Simply plug everything in and the Moon Controller does the rest. The Moon controller can also be used to manually dim the moon lights from 0 to 100% with no flickering. Because changing the controller to manual mode does not interfere with the timing of the moon cycle, you can feel free to play with the moonlight at any time. When the controller is turned back to auto mode, the correct amount of time will have elapsed. Furthermore, the controller will remember its place if the power goes out (though the cycle will not continue during the outage). Best of all, all this functionality is in a 1" by 2" package that can be mounted virtually anywhere.
