Reef Chemistry Question of the Day [HASHTAG]#192[/HASHTAG]
You are cycling a reef tank by adding ammonia (as ammonium hydroxide) and using dead rock. Three times you add exactly 1 mg/L ammonia, and three times it eventually all is converted into nitrate, forming 10.9 mg/L of nitrate, which you accurately detect in the water.
Before any additions, the alkalinity of the water is 9 dKH (3.2 meq/L).
What is the alkalinity after all of the ammonia has been converted into nitrate?
A. 10 dKH (3.6 meq/L)
B. 9.5 dKH (3.4 meq/L)
C. 9 dKH (3.2 meq/L)
D. 8.5 dKH (3.0 meq/L)
E. 8 dKH (2.9 meq/L)
Good luck!
