JDavis, you may think I'm crazy but you may be able to turn the whites down to around 15%. Let everything acclimate then slowley bump them up over time, like 2% a month to 25%. These lights have a lot of white and are very powerful. You can grow stuff like crazy but your color might suffer. Its more easy to kill coral with to much light than not enough. Keep your blues high along with the UV. Give your coral time and I think you'll be quite pleased. Youve got to find this light spectrum that grows the zoozenthellia. I've had my light for several years and learned this the hard way. I"m finlally seeing that crayon color we are all looking for. It takes a lot longer for color to come back after you've bleeached something.
