Comments: The 10,000K is actually with a rather pinkish cast, not really pure white. OK only if that's what you want.

Comments: Lights make aquarium look great. Not quite as bright as metal halide but economically a great alternative. I use 2 fixtures which really help brightness and color. I don't have a water cooler but use a small fan in sump to keep water temp ideal. I only have soft corals. Beware that these bulbs last about 9 months. After that, the red slime algae appears and replacements are needed.
