Overview ›
The LGND Aurora UV‑C Internal Steriliser is a fully submersible UV‑C unit designed to help maintain clear and healthy aquarium water. UV‑C light at approximately 253.7 nm helps control free-floating algae and microorganisms as water circulates around the lamp housing.
The Aurora can be installed inside an aquarium, sump or permanently filled filter chamber. Its programmable controller allows an operating time of up to 8 hours to be selected in 30-minute increments, together with adjustable interval-day settings. A six-segment indicator monitors the calculated UV‑C lamp service life.
The compact housing, high-grade quartz glass and waterproof silicone sealing system provide reliable submerged operation. The unit can be installed vertically or horizontally using the supplied suction cups.

Directions ›
Attach the LGND Aurora vertically to the side or rear glass of the aquarium using the supplied suction cups. Position the unit in an area with strong water circulation, preferably close to the filter outlet, so that water flows freely around the protective housing.
Ensure that the complete UV‑C lamp assembly is fully submerged and that the housing openings remain unobstructed. Install the unit where fish and other aquarium inhabitants cannot come into direct contact with the lamp or the UV‑C light emitted through the housing openings.
Install the Aurora inside a sump chamber that remains permanently filled with water. The unit may be attached vertically to the side or rear glass or installed horizontally on the bottom of the chamber.
Position it in an area with strong and continuous water circulation. Ensure that the complete lamp assembly is fully submerged and that the protective housing openings are not obstructed by equipment, substrate or other objects.
Refer to the supplied operating manual for controller settings, operation, cleaning and maintenance instructions.
