So couple weeks ago I had to move my trumpet coral bc my RFA smothered it. It’s finally showing signs of coming back 🙌

My favia coral however, went from vibrant and thriving to suddenly turning brown. I had a lot go on in that time… new wave maker that I was fine tuning placement, treating Cyo-Control for a relentless Cyano outbreak… any ideas why it might have suddenly lost its color?
