Frequently Asked Questions

Do I need lighting for a saltwater tank?

Saltwater aquariums benefit from having lighting. Although you can run a fish-only tank without, providing a light source helps encourage natural behaviour in fish by providing them with a day/night cycle. If you are growing corals, you will need to provide suitable lighting to support photosynthesis.

Can I use freshwater lights in a saltwater tank?

You can use freshwater lights in a saltwater tank if you are only keeping fish. Freshwater lights do not produce the blue and violet spectrum that is required for coral growth and photosynthesis. Freshwater lighting solutions are typically warmer and full-spectrum, which can be used to illuminate the tank enough to see your fish.

Why choose LED marine lights?

LED lighting is superior in energy efficiency, and is commonly chosen by reefkeepers thanks to having a better control of the spectrum, an ability to mimic natural sunlight, and an extended lifespan.

Which lighting is best for marine tanks?

It is best to choose LED lighting that is marine-spec and suitable for it's intended use, whether that be for growing corals or providing fish with a day/night cycle.
