Aqua Medic Aqualine T5 Reef White 15000ok 80W — Blue-white 15,000 K T5 HO tube for 150 cm reef aquariums
A 10,000 K tube can look a touch yellow over a reef, and many keepers want a whiter, bluer daylight that still lights the corals hard. Aqua Medic Aqualine T5 Reef White 15000ok 80W (SKU: AB88713) is the 80 W, 145 cm Reef White 15K tube in Aqua Medic’s aqualine T5 range, a high-output (HO) fluorescent lamp for saltwater aquaria. Aqua Medic describes its light as extremely bright blue-white, providing ideal illumination for the saltwater aquarium, with a spectrum chosen to encourage strong coral growth. Reef Builders, reviewing the range, described the Reef White 15K as a crisp white tube with a 15,000 K look. At 145 cm it suits fixtures over reef tanks of about 150 cm.
Unlike the Reef Blue tubes, the 15K is designed to stand on its own: Aqua Medic states it can be used as the sole light source for an aquarium, or in combination with aqualine T5 Reef Blue for a deeper blue tone. In a six or eight-tube fixture over a 150 cm display, alternating 15K and Reef Blue tubes gives a blue-white reef look, while a mostly 15K line-up reads brighter and whiter. Reef Builders’ tests used the 15K at the front of mixed four-tube line-ups with Reef Blue and Reef White 10K. At 80 W each, a full fixture of these tubes is a high-light set-up suited to stony corals. The lamp has G5 bi-pin ends and needs an 80 W T5 HO ballast at 145 cm. Output falls steadily with age, and reef keepers usually relamp every nine to twelve months, staggering the change so corals are not shocked by a sudden jump in intensity.
