As the spa fills with water use a bottle of First Step to prevent staining of the spa surface by dissolved metals in the water. Add 1 bottle per 600 gallons of water and allow to circulate in a filled spa for 60 minutes before proceeding with other chemicals. First Step aids in the removal of iron, copper, and other metals and minerals from the water.

Note: Spa Sauna Direct only ships pool and spa chemicals within the continental United States.
