When filling your hot tub with tap water it is important to use a good metal sequestering agent before adding chlorine and bromine. St. Cyr’s Stain and Scale treatment helps your spa filter out metals like copper and iron commonly found in tap water.
Copper and iron can cause water discoloration and water line staining.
It is recommended to always add Stain and Scale when you fill your spa or add a significant amount of tap water. Run the spa for 24 hours without adding chlorine. Then rinse your filter, then add chlorine.
