D-D Giesemann Powerchrome 24 Inch 24W AquaBlue+ T5HO Fluorescent Bulb

Light dependent corals in the sea are inhabited by so-called zooxanthellae, single-celled algae, which provide the host through photosynthesis with nutrients. Depending on the natural location of the coral (and depending on their depth), there is a more or less blue coloured light, to which the zooxanthellae have adapted. Apart from the increased amount of blue in the light spectrum there is as well a sufficient light intensity required.

POWERCHROME aquablue + is the ultimate blue/white light spectrum for brilliant colours from your corals and fish. It is ideal in combination with the ACTINIC+ or PUREACTINIC to produce exceptionally beautiful color effects and the ideal light for all marine creatures that live in salt-water and reef aquariums. A special 60:40 combination of 6000K and 22000K (approx) phosphor blend. It is specifically designed for reef aquariums mimicking sea water to a depth of one to twenty meters.
