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.
- Powerful 4-in-1 Formula - Kills bacteria, prevents algae, reduces odor, and restores clarity with advanced HTH chemistry.
- Crystal Clear Results - This Cal hypo powered swimming pool shock treatment clears cloudy water in just 24 hours for sparkling confidence.
- No Cyanuric Acid - Cal Hypo formula avoids overstabilization or chlorine lock while protecting pool health, so your chlorine stays effective longer
- Shock Weekly with Cal Hypo: For best results, shock weekly with HTH™ Cal Hypo Shock Advanced.
- Fast-Dissolving Ease - Quick-dissolving cal hypo pool shock makes weekly care simple, reliable, and stress-free

Pool was in chlorine lock due to just opening for the season. This product quickly cleared the water and allowed for the addition of chlorine in a few days. Highly recommend.

HTH Pool Shock
As always, if you've got a pool. you've got to have the shock and usually a good bit throughout the entire summer. This shock gets the job done %26 it's less expensive than some other brands. I highly recommend it. I will be buying more for certain.
