We recommend using the Tunze Eco Chic Refugium Light 8831 as a refugium light. This light is submersible and can easily fit into the back chamber of a nano tank or in a sump. You can put the light in vertically or, using the magnet holder, attach the light so it is situated horizontally.
Though we champion this unique light as a refugium light, it could also be used as a planted tank light for aquariums up to 15 gallons.
Can be used in air or in water. When used in water it is more effective as light is not lost through reflection
