Possible RTN on SPS

[sps waters]

I fed Polyp-booster from polyp lab to my tank last night and this morning some of my sps are showing signs of RTN were it touched the coral. Specifically my Starbust monti and my green and purple monti. Any ideas if it’s RTN and should I try to frag the good parts to salvage it?

Bump.

The tank looks too young by looking at the color of the rocks. I could say is less than 3-4 months old. It needs time to establish, there's a lot of parameters swings and the corals do not like that. If you're not measuring your nutrients do not feed your corals. Keep doing the basics, water change, monitor your alkalinity, and give the tank time to mature.

The tank is 4 months old, but the only parts that died are the parts the the polyp booster touched oddly enough. Everything was doing great with lots if growth. All parameters stable.

I would avoid adding anything but fish food and alk and calcium supplements, unless some test or some verifiable reasons dictates otherwise. Give the tank time to mature. Leave the coral alone and it will recover. Looks like it was irritated.
