LPS Browning Out

[mwbeach]

Good Morning, I just put a Chinese LED fixture on my tank and before had 4 t5 bulbs. I noticed today that the LPS corals are looking a little brown and loosing their color. Am I giving to much light or not enough? I am running the Blue LEDs on 40% for 8 hours and the whites on 15% for 6 hours. Thanks

Too much. Acclimate them slowly. That browning is lps bleaching.

Thanks. What percentage should I do and for how long?

I would put the t5 back on personally, but if not I would run whites at 5% for 3-4 hours and blue 25% for 6 hrs for 2 weeks then raise up 5% each week
