Help on coral

[Courtney Lovell]

This guy is usually red and gets light colored on parts that are growing. Now he looks grey???

Looks like a very unhappy Montipora cap to me. What are your parameters and how long have you had it for? Also it looks like it is covered in sand which irritates the coral.

All water levels are good
I have had him for about 5 months. I keep moving the sand my goby keeps trying to bury him.

Potassium is low. Red monti caps pale out bad when K is way low. Test Potassium

Happy to report he is red, happy, and growing again. Thanks for all your help
