Description
Aqua Medic Aqualine T5 Reef Blue 80W — Long 145 cm blue T5 HO tube for deep and 150 cm reef displays
Blue light from a fluorescent tube loses intensity with depth, so a large, deep reef needs the most powerful tubes the fixture can take. Aqua Medic Aqualine T5 Reef Blue 80W (SKU: AB88703) is the 80 W, 145 cm blue tube in Aqua Medic’s aqualine T5 range, the largest and highest-wattage Reef Blue, made for saltwater aquaria of about 150 cm. Aqua Medic states that it emits almost exclusively blue light between 400 and 500 nm with a peak at 420 nm, and that these wavelengths enhance the growth of many coral species. Paired with Reef White 10K or 15K, according to the maker, it gives the aquarium a natural appearance.
At 80 W per tube, a six or eight-tube fixture over a 150 cm display delivers a lot of light, so the blue share is usually set at half or a little more of the tubes, depending on how blue the keeper wants the tank to look. The longest tubes are often run on a separate circuit from the whites, lighting the tank blue for an hour before and after the main period, which also shows off coral fluorescence in the evening. On deeper tanks the higher wattage helps light reach corals placed lower on the rockwork. This is a G5 bi-pin T5 HO lamp and needs a ballast rated for 80 W at 145 cm. Fluorescent output fades steadily with use, so reef keepers usually relamp every nine to twelve months, staggering the change across the fixture.
Usage & Application
When to Use
- 150 cm reef displays: Fixtures that take 145 cm, 80 W T5 HO tubes.
- Deep aquariums: More output to reach corals lower in the rockwork.
- Blue-only periods: Dawn, dusk and evening viewing on a separate circuit.
- Relamping large fixtures: Replacing the blue half of a six or eight-tube unit.
Installation & Setup Guide
- Match the ballast: 80 W T5 HO, G5 sockets spaced for 145 cm tubes.
- Handle long tubes carefully: Support the middle when lifting a 145 cm lamp in or out.
- Seal against splash: Seat the pins fully and refit the end caps over a reef tank.
- Stagger the change: Renew one or two tubes at a time so corals adjust gradually.
