You're right. The colour change in a coral could mean any number of things, good and bad. I know my tank and its inhabitants well though, and I know the difference between a "good" response and a "stress" response. This was a stress response. In all my years of reef keeping, carbon dosing is new, and IMO a fad. People never had a problem keeping sps before carbon dosing.
