About 20 years ago, we had 5500k Halides that produced this thin white light much like todays' 10k LED's. All your corals were kinda pale, dull, and boring. You could get really excited if some of those powder blue mushrooms from JP Burleson found their way into your tank. Green star polyps and Trachyphyllia were the "wow' colored corals that looked brighter than the rest. When VHO actinic came around, it was like a black light went off in your bedroom.

The reality of this whole topic is that corals in the wild are nowhere near as colorful as they seem to be in our tanks. Be thankful that now you have a powerful light that costs pennies to use and delivers very little heat.

Start buying and growing corals that look good under white light. Urine looks kinda boring in the toilet, but when you turn on the black light, it glows pretty nice.
