this is a quote from a service guy...
"I've seen this type of bleaching time and time again with LEDs. My service company has used many of the top brands and without fail, the coral health over time just goes down hill. Sure they look great under the blues but as soon as you look at them under any sort of normal light, you can see that they are really washed out. The only LEDs I've ever had any sort of long term success with has been the reefbrites and even with those, I had to use Aquablue t5s with the LEDs to keep the corals happy and colorful. I think there is alot of promise in LED technology, but for long term coral success, I recommend staying with the tried and true t5s, MH and sparing LED use to accent color"
