- Is this light strong enough for corals?
- It suits soft corals and low-light setups in nano tanks. Demanding stony corals usually need a more powerful reef fixture.
- How is it controlled?
- Through the FluvalSmart app over Bluetooth. You set schedules, brightness and blue/white balance from your phone.
- What size tank does it fit?
- It is designed for nano tanks and small footprints. On wider tanks the spread will not cover the full length evenly.
- Does it need a separate controller?
- No. The Bluetooth app is the controller, so no extra timer or dimmer is required.
- Can I set a sunrise and sunset schedule?
- Yes. The app supports daily schedules with gradual ramping between settings.
- Is it for freshwater tanks too?
- It is built for marine and reef tanks. Freshwater keepers are better served by a planted-tank light with more white output.
