Lighting for marine aquariums is one of the most important pieces of kit you’ll buy, as it directly affects coral growth, colouration and the overall look of your reef. Modern marine lights (mainly LEDs, plus T5/hybrid options) are designed to deliver the right spectrum and intensity for soft corals, LPS and SPS, with controllable blue-heavy settings to bring out fluorescence and create natural dawn/dusk effects. When choosing lighting, consider the size and depth of your tank, the types of corals you keep, and whether you want simple plug-and-play units or fully app-controlled fixtures. Get it right, and your corals will thrive with great colour, growth and that classic reef “glow”.
