About this item
Product details
HTH Pool Care Shock for Swimming Pools, Boosts Chlorine Levels, Cal Hypo Formula, Pool Chemicals, 5.5 lbs
HTH® Shock is the original swimming pool shock designed to boost chlorine levels and kill bacteria and algae for a clean, clear pool. 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 based formula in HTH® Shock provides chlorination without adding extra CYA for a beautiful sparkle all season. This pool shock is great for all pool types and won't fade your pool liner.
How To Use HTH® Shock Follow the on-pack instructions according to your pool size to add HTH® Shock directly to swimming pool water or skimmer. Make sure to use a clean, dry scoop. For best results, apply HTH® Shock as part of your weekly pool care routine to keep free available chlorine levels between 1 and 4 ppm.
- Multi-use pool shock with Cal Hypo
- Use weekly to solve 90% of pool water problems within 24 hours
- Fast-acting and fast-dissolving
- Visibly brilliant sparkle
- This Cal Hypo based formula sanitizes without adding cyanuric acid (CYA) to prevent over-stabilization or chlorine lock.
- This product is great for all pool types including vinyl-lined pools and salt water systems.
