Vanishing Act Calcium Remover is a bag that can be placed over your spa’s intake to remove calcium from the water. This, in turn, increases the lifespan of your spa.

NOTE: If you find moisture inside a “Vanishing Act” calcium remover bag for a hot tub, it’s completely normal; the product is designed to be slightly damp due to the manufacturing process and the resin inside that absorbs calcium, so you can usually just rinse it off and use it as intended.
