I’d do a water change and get the DkH stable.

I’m dosing KH over a 24 hour period. Readings are taken every morning at the same time .

The .02 phosphates is possibly the culprit. Mine came when phosphate was .02. The margin of error in testing could mean it zeroed..or possibly .02 wasn't enough..I'm not positive on what caused mine. Nitrates were around 7 at the time as well. This is likely the cause of the coral turning white as well. Again, I'm no expert so I'm sure others can add more info

Agree if 0 most definitely is a problem for the coral. 0 phosphates could lead to a dino outbreak
