When we first got involved in the spa & hot tub business back in the early 1980's, we knew that we needed a spa additive that would provide additional benefits for our customers health & well-being.  We chose Magma Onsen.  Now we're proud to once again offer it to you.

Magma Onsen is made from the volcanic salts & minerals found at the world-famous Omijigoku Onsen (or natural mineral spring) in Beppu, Japan.

Both men & women rave about the minerals' ability to soften skin as well as aid in relaxing tight muscles & body joints.

Light, clean fragrances are then added to further enhance your soaking experience.

Magma Onsen contains Potassium, Magnesium, and other Volcanic minerals.  pH balanced to sooth your skin. 

Will not harm or clog filters & other spa parts.

Use 1 packet (about 2 tablespoons) per 300 gallons.

Available in 15 g packets & 500 g (17.6 oz) recloseable jars
