This swimming pool shock is specially formulated for vinyl pools. Our vinyl pool shock requires no pre-mixing, dissolves quickly with no residue, and won't fade your pool's vinyl liner. Excellent for routine pool shock treatments throughout the season. This pool shock can also be used in concrete pools. Use in place of Super Pool Shock to keep your pool liner looking new and vibrant!

  • 56% available chlorine, 99% sodium dichlor. 
  • Comes in 10 oz. bags; one 10-ounce bag treats 6,200 gallons of pool water. 

Because of its preventative effects, you still need to apply pool shock treatments even when pool water looks clear and chlorine is consistently used.
