The Reef Brite Aqua Viewer is another nifty little tool for viewing your aquarium in closeup. But the Aqua Viewer is more than a hand-held magnifying glass, as it also has a ring of LED lights to illuminate your corals, fish, and invertebrates for better viewing. The 2.5″ lens on this viewer magnifies up to 2.5x, and has 24 LEDs, of which half are white and half are blue. The LEDs are also on independent channels, so you can view in either all-white, all-blue, or both. A carrying case is included with the viewer, and the retail price is around $50.
