Who Gives A Fish Forums

I agree with reefkeeper1. Low nutrients can bleach SPS. I'd also look at your lighting. Radions are strong, and 60% might be too much if your corals are high up. Try reducing intensity to 50% or raising the lights a bit. How's your flow? Acros need random, turbulent flow to thrive.

Glad you're taking action. Keep us posted on how it goes. Sometimes corals bounce back surprisingly well. What's your QT setup like? Got a light over it?

I'm so sorry you're dealing with this. Brown jelly can spread quickly, so isolation is key. Have you noticed any other corals acting off? Sometimes it's a sign of broader issues. Sending good vibes your way.
