Extra Substitute Shock 1 lb. Granuels
Product Description
PRODUCT LABEL MAY VARY. 1 lb. bag of 99% sodium di-chloro-s-triazinetrione hydrate, (55% Available Chlorine) shock that is used weekly to bi-weekly, or when a little extra oxidizer is needed for tough cloudy water. It dissipates rapidly, therefore rendering the water back to a non-chlorine status. Always test water if chlorine free (level) is a user issue. Great substitution for Pristine Extra Shock, or Brilliance Spa Granuels.
