new leds

[Erak82]

I bought new leds about 6 months ago. I got two reef breeder value fixtures over my 75gal. I started them low like 15% about a month and a half went to 30%. This started to bleach a few corals so i turned it back down for awhile. Then instead of turning the whites up i just turned the blues up i think they were about 50%. I have noticed like two months later all my candy cane colonies have flesh receding on the stalks could this be caused by the blues? It seems i will never be able to turn these lights up. Any suggestions

Gonna need other params also.
I'd definitely turn the whites up to at least 30%. So you want to turn them up slightly a week at a time, not jump up, just slightly turn them up until the coral get used to it. You probably will not ge them to 100%, not many run em that high. Mine aren't running at 100% My whites are at 55% and the blues at like 80%
