Reef Chemistry Question of the Day #57
Assume that you are keeping a reef aquarium by supplying all of the alkalinity needs using limewater (kalkwasser) made from pure calcium hydroxide. That is, the alkalinity is maintained at 9 dKH by slow and steady dosing throughout the day and night.
You are also not doing any water changes or adding any other supplements.
Which of the following does NOT take place in your aquarium compared to before you started limewater dosing?
A. Calcium declines over the long term.
B. Calcium rises over the long term.
C. Magnesium declines over the long term.
D. Bicarbonate declines over the short term.
E. Carbonate increases over the short term.
Assume that long term means months since initiating dosing and short terms means hours since initiating dosing.
Good luck!
