About This Product
About This Item HTH Shock Advanced is the powerful 4-in-1 formula with Cal Hypo that kills and prevents bacteria and algae as well as reduces chlorine odor and irritation for crystal clear, healthy water. Traditional chlorine products contain cyanuric acid (CYA). When too much CYA builds up, it can cause overstabilization or chlorine lock and cloud your water. The fast-acting, fast-dissolving Cal Hypo formula in HTH Shock Advanced provides chlorination without adding extra CYA for a beautiful sparkle all season. This product is great for all pool types and won't fade your pool liner. How To Use HTH Shock Advanced Follow the on-pack instructions according to your pool size to add HTH Shock Advanced directly to swimming pool water or skimmer. Make sure to use a clean, dry scoop. For best results, apply HTH Shock Advanced as part of your weekly pool care routine to keep free available chlorine levels between 1 and 4 ppm. About HTH Pool Care HTH was developed with the pool owner in mind. We know that maintaining your pool water can be a lot of work. That's why we're here every step of the way, helping you clear the uncertainty from pool care.

Questions & Answers
Dose this shock works in vinyl pool?
Hi Ramin, yes, this shock can be used in a vinyl pool. Be sure to balance the pH before application and brush undissolved residue off the bottom of the pool. Please feel free to give us a call at 866-484-7665 or chat with us at hthpools.com, if you have any questions. We're Here to Help!
Can this be added directly to a vinyl lined pool or does it need to be dissolved first?
Hi Heidi, this shock should be added directly to the pool, not pre-dissolved. To keep the liner safe, it's always recommended to balance the pH prior to use, and to brush up any undissolved granules that fall to the bottom of the pool. If you have any further questions, please feel free to give us a call at 866-484-7665 or chat with us at hthpools.com. We're Here to Help!
What is the available chlorine per weight? Why don't you publish it?
Hi Walt, the available chlorine of this product is 56%. One pound of HTH Shock Advanced in a 10,000 gallon pool will yield 6.72 ppm of free available chlorine. If you have any more questions, please feel free to give us a call at 855-484-7665. We're Happy to Help!
Why is this shock in the 12 pack at $3.95 per lb. listed as "Out of Stock," but this 6 pack is available at $5.37 per lb.? Will Home Depot price match its own product being that it's the exact same product just the quantity is packaged differently?

However, for product performance, quality and use of our products, feel free to reach out to us thru this platform, or by calling Consumer Engagement Team at 866-484-7665, or chat with us thru the HTHPOOLS.com website.
