so for the mag portion of this recipe from reef keeping i would mix epsom salt and this BRS Bulk Magnesium Sulfate Aquarium Supplement - Bulk Reef Supply or this BRS Bulk Sodium Bicarbonate Aquarium Supplement - Bulk Reef Supply.
Dissolve Epsom salts (3 cups) and magnesium chloride hexahydrate (5 cups) in enough purified freshwater to make 1 gallon total volume. There will likely be a precipitate that forms even if you fully dissolve both ingredients separately. That precipitate is calcium sulfate (calcium as an impurity in the magnesium chloride and sulfate from the Epsom salts). It is fine and appropriate to dose the precipitate along with the remainder of the fluid by shaking it up before dosing.
What is magnesium chloride hexahydrate considered? thx
