Why do you only want 250? My Montiporas grow like weeds with crazy polyp extension because they’re getting blasted with 450-550 par. Sps can handle a lot of light as long as your chemistry is correct and stable. Knowing what I know, if I were you, I would set your spectrum to at least 60 watts for each fixture, do a 50% 4 week acclimation period. 3 hour ramps up and down with 5-6 hours of peak time.
Now there a lot of things, especially in my experience, that can cause stress to sps. I absolutely do not recommend gfo, carbon dosing, or any other nutrient media. I had many issues from these kinds of products because I was chasing low nutrients. Now the only nutrient exports I have are my skimmer, chaeto, and my corals.
I don’t think you have enough light for your sps at the moment but it would takes a couple months for it to die. I don’t know how long it’s been showing signs of stress but since it’s a wild piece it could be a number of things. It could be in shock because it came from stable but different chemistry, temperature and lighting. It could also have a pest on it. I would investigate all of these things as well.
I wish you the best
Makes me look forward to my vacation at Oyster Bay, Trewlony Parrish in July
