I’ve got a miagi tort frag that i just acquired and im not super knowledgeable with SPS. But ive noticed some green hair algae growing out of one the polyps and that section of the coral has also turned white. Is this something that i should clip off? I know when they turn white it’s a sign of bleaching/coral die off. Should i be worried? Any help is appreciated!

I agree with what the other 2 have said. I will add that if you see the tissue continuing to receede or die off I would clip the dead bit off with a bit of extra margin to prevent further spread
I like hydrogen peroxide as a dip for algae and a very soft bristle tooth brush, humble fish has a good guide for h2o2 dip mixing ratios , I am also a big fan of underwater wonders dip (which I think is potassium chloride) and i use iodine when a coral has an open wound or some damaged flesh
Hmm 🤔, maybe try carefully removing the algae as much as you can and double check to make sure water parameters are ideal, also check to see if it’s getting a decent amount of flow all around.
