You know my tank has been stumping me latley I noticed ph was 8.48 the other day. What symptoms did you observe? Browning? RTN? Poor polyp extension? Bleaching?

My apologies, I should have specified that this is for a school project. I wanted to know the effects of high ph levels on coral reefs. I tried to research it on google, but couldn't find much. Anything helps, thank you
