About this item
Product details
HTH Pool Care Shock Advanced for Swimming Pools, Prevents Bacteria & Algae, Cal Hypo Formula, Pool Chemicals, 1 lbs
HTH® Pool Care Shock Advanced 1lb 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 over-stabilization or chlorine lock and cloud your water. The fast-acting, fast-dissolving Cal Hypo formula in HTH® Pool Care Shock Advanced 1lb provides chlorination without adding extra CYA for a beautiful sparkle all season. This product is great for all swimming 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.
- Multi-functional shock treatment for weekly use
- Prevents bacteria & algae
- Use weekly to solve 90% of pool water problems within 24 hours
- Restores crystal clarity in 24 hours
- Visibly brilliant sparkle
- This Cal Hypo based formula sanitizes without adding cyanuric acid (CYA) to prevent over-stabilization or chlorine lock.

Works Great
Our pool suddenly went green and I needed shock fast. Looked up Walmart same-day delivery and this was a good price, delivered that afternoon. After brushing %26 vaccuuming I immediately used one pack, then the next day brushed %26 vaccuumed again and added a second pack. Pool looks great!

Great shock
This pool shock is fantastic! Typically, I need to use three bags of my usual brand, but with this product, I only needed two. It left the water looking crystal clear and beautifully blue.
