New light, now corals closed!

[2g2ner]

I went from 175w of PC to 96w of T5. My corals were going fine with the PC bulbs but not growing any. I upgraded 3 days ago and my corals opened great the first day, but now there barely opening. My water quality didn't change and my coral list is a few leathers and s GSP colony. Why is this happening?

Did you acclimate them to your new light? Shorter duration or screening over the tank?

No. I didn't know I had to do that for light =(
