Iread somewhere that SPS corals get little additional benefit from more than 6-8 hours of lighting. Do some checking in the SPS corals forum. You might try reducing lighting gradually and see how the corals react. My judgement of coral's growth is the uptake of Alk. I use a little over 2 dKH /day.

I feed quite heavy - my tangs eat at least a 4x8 sheet of Nori daily.

I have a ATS and also dose carbon to keep NO3 and PO4 under control.
Last reading were 5 and .07

My last harvest after 6 days was 400 grams of algae. See pictures. My screen is 9x10
