Simply harvest a handful of algae periodically to maintain the biological balance of the aquarium. The Tunze 8831 produces a spectrum specifically calibrated to accelerate this growth in any refugium or sump compartment.\u003c\/p\u003e\n\u003cp\u003eSubmersible lighting eliminates reflections on the water surface, making the light source more efficient. An immersion of 1 to 2 cm (0.4\" to 0.8\") is sufficient. Underwater operation also helps to relieve aquarium heating thanks to the heat emitted by the LED.\u003c\/p\u003e\n\u003ch2\u003eInstallation and control\u003c\/h2\u003e\n\u003cp\u003eThe magnetic holder allows the lamp to be fixed in the center of the fixture or at the end of the cable, in any orientation.
