Is It Normal for SPS Corals to Lose Color After a Tank Transfer?

Hey everyone,


I recently moved my SPS corals to a new tank setup (same lighting brand, same salt mix, similar flow), but I’ve noticed that some of them—especially my acros—are starting to lose color and look a bit faded. Polyps are still extending, and parameters seem stable:


  • Alk: 8.3
  • Calcium: 420
  • Mag: 1350
  • Nitrates: ~5ppm
  • Phosphates: ~0.03ppm

Could this be stress from the move, or should I be looking at possible lighting acclimation or micro parameter swings? I'm using Radion G5s at 50% intensity, same as before, but maybe the spread is different?


Has anyone experienced similar fading after a transfer, and what helped you bring the color back?


Thanks in advance!
