High Output T5's are better to use in your aquarium lighting than the regular T8 as they have increased water penetration and are more efficient. You don't lose the illumination at the bottom of the deeper tanks. The greater intensity, deeper penetration and Higher output allows you to stock your tank with a wide range of soft corals and allow them to flourish which was not possible with T8 Fluorescents.

It combines the phosphors of a Blue Plus tube with a 10000k full-spectrum daylight bulb. This bulb is great as a standalone bulb in smaller tanks or running alongside an iQuatics Blue Plus or the Actinic range in larger setups. The Aqua Blue 50:50 has a mixed spectrum of useful light energy providing maximum PAR for ideal coral growth condition. With an overall blue tint to the visual output, your tank will appear in its natural beauty with your corals located at both the higher and lower depths of your aquarium. It helps to balance out the washed out yellow hue in your aquarium. The iQuatics Aqua Blue works well as a supplement to metal halides or in combination with iQuatics Marine White 14000K.
