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?
