The Zoo-Med Coral Sun High intensity
actinic lamp is ideal for marine aquariums, reef tanks, and African cichlids.
High intensity actinic lamp with strong emissions in the short wavelength region
of the spectrum, peaking at 420 nm promotes the growth of zooxanthellae algae,
essential for the growth and well being of all photosynthetic corals and
invertebrates. Output of this lamp closely matches the absorption peak of blue
chlorophyll used in photosynthesis. Long lasting: Effective for up to 10,000
