Scoly help

So in the past 2 days my scoly has become very unhappy and looks like its dying. The only thing that has changed in my tank is I got a Kole Yellow eye tang. I feed the scoly at night when it has its tentacles out but still doesn't look good. Only thing that was high was the KH..
9.6dkh .. PH is 8.2 Nitrites and nitrates were just above zero. I did a 10 gallon water change tonight to get that back to zero. No phosphates I dose with Reef energy A/B every day 4mls each in my 65g tank. i have a bunch of lps and sps that haven't changed but my RTBA just split for the 3rd time.. Any thoughts?

 

bet your torch is stinging it

 

Just moved it there tonight. Wasn't anything around it prior. Moved it to a shadier spot with lower flow.
