How to use
Install the fixture above the aquarium at a height that provides even coverage across the water surface, following any included mounting guidelines. Pair the LED light with the compatible smartphone app using Bluetooth, then configure the daily schedule and spectrum settings. Start with conservative intensity and acclimate plants or corals by gradually increasing runtime and brightness over several days.
