I have a 75 gallon mixed Reef and two vpar Spectra lights. I run my blues at 90% all around And the whites at 65% on one side and 70% on the side with the SPS. I've had my Coral in for 2 months now and everything seems to be doing pretty good I'm thinking you need to brighten up a little bit but slowly because I know especially SPS corals have a hard time with major light adjustments. Not sure if this helps at all but seems to be working pretty good for me to this point :-)
By the way are you feeding your corals at all and if so what method are you using?
