Is the PAR too high for my SPS?

I picked up these SPS back in May and they morphed pretty hard from the reds and orange that they arrived with.

Back in July, I ramped my lights up to give them about 120 - 150 PAR and I'm not sure if I'm "chasing numbers" or they're starting to bounce back. These are my first acropora and millepora, so besides what I read and see online, I don't have any real world experience yet.

Look as if they are bleaching, although not dead and still a chance at survival. It’s hard to see exactly how high of light would be there, and could not be the reason or only reason they are in that condition. What is the lights par where they are? What are your other parameters?

didn’t read your post enough… i see your par is 150, this would be on the lower end for these guys and they’d prefer to be in 2-300 range for your acros, it seems you also have a stylo that “would” or could be okay in that par. what are your other parameters though?

Hey and welcome! 150 par is pretty low for an acro imo.
 
PAR seems low, not high.
But also dependents on spectrum. Its not as simple as chasing a number.

I keep most of my corals at 400+, but with a very “yellow” spectrum. And yes, most corals includes LPS and softies.
 
How old is your tank and what are the parameters? Those are the usual places to start.

As noted above, a Par range of 120-150 is very low for SPS. I have an SPS dominant tank and try to keep most of the coral in 300-400 Par.

From the tank pictures it seems like your rockwork has a lot of fuzzy growth. I am not sure if that is an issue or not but it may be worth looking into.
