Reef Chemistry Question of the Day [HASHTAG]#125[/HASHTAG]
Under which of the following conditions is an exposed coral skeleton most likely to begin to dissolve (all other conditions equal natural seawater)?
A. Calcium 210 ppm, alkalinity 2.5 meq/L (7.0 dKH), pH 8.2
B. Calcium 420 ppm, alkalinity 1.0 meq/L (4.2 dKH), pH 8.2
C. Calcium 210 ppm, alkalinity 1.5 meq/L (4.2 dKH), pH 8.5
D. Calcium 300 ppm, alkalinity 2.0 meq/L (5.6 dKH), pH 8.2
E. Calcium 500 ppm, alkalinity 3.0 meq/L (8.4 dKH), pH 8.2
F. Calcium 420 ppm, alkalinity 2.0 meq/L (5.6 dKH), pH 7.6
Good luck!
