How to Add Magnesium Chloride to Your Spa

Measure out 1 lb. of magnesium chloride flakes or oil into a container. Pour the magnesium chloride directly into the spa water. Add another pound of magnesium chloride to the spa and repeat until the desired level of magnesium chloride is reached. Typically 2 to 4 lbs. of magnesium chloride are used for a single spa treatment.

Turn the spa on, and activate the jets to begin circulating the spa's water. Allow the spa to circulate for several minutes to dissolve the magnesium chloride.

Stir any undissolved magnesium chloride flakes resting on the bottom of the spa by hand or with a brush. Stir until the residue is fully dissolved.
