Reef Chemistry Question of the Day #7
Why can't you add magnesium chloride to limewater (kalkwasser) to get a supplement that adds calcium, alkalinity and magnesium?
A. The calcium will precipitate as calcium chloride.
B. The magnesium will suppress the calcium solubility, leaving much less calcium in solution.
C. The chloride will clog the drip tip.
D. The magnesium will precipitate as magnesium hydroxide.
Good luck!
