The Fluval Reef Nano 4.0 is a full-spectrum LED light for small saltwater aquariums, built around the actinic range corals use to photosynthesize and color up. Its independent color channels, programmable 24-hour cycle and preset environments are all set through the FluvalConnect app over Bluetooth, with no onboard controls. It is IP67-rated against water and dust and has a glass lens, and the mount adjusts up, down, forward, backward and side to side. It suits nano reef keepers who want app control and a compact footprint; larger tanks and anyone who dislikes phone-only control are better served by bigger fixtures with physical controls.
