My question is purely to satisfy my scientific curiosity. In the wild reef, does PH change much between night and day? Do other parameters?
Yes, and not all ocean water will test exactly the same. It will differ around reefs and coastal areas. But the daily changes are extremely small, the ocean is extremely stable. Even temp change occurs very slowly over a long period.
