Reef Chemistry Question of the Day #79
You determine that your reef aquarium is low in magnesium, and you begin to wonder what the most potent solid magnesium supplements might be.
There are many to pick from, and it seems a perplexing question...
If you add 1 gram of each of the following to a 100 gallon reef aquarium, which of the following will cause the largest boost to the magnesium ion concentration, and which will cause the smallest boost?
A. Magnesium hydroxide
B. Magnesium oxide
C. Magnesium chloride
D. Magnesium chloride hexahydrate
E. Magnesium sulfate
F. Magnesium sulfate heptahydrate
For purposes of this question, ignore anything else the non-magnesium part of the additive might do. So you are not picking the best additive, just the most and least potent ones.
Good luck!
