Have to use clarifier after using this product?** A: Dump into a bucket of water from pool and dissolve then walk around pool adding the contents of bucket into your pool, if you stir the shock in bucket for a few minutes it dissolves. **Q: Can i use it for salt system? i heard we cant shock salt pools with calcium products** A: It is recommended you dissolve the shock in a bucket of water first, this product is very good when opening pool, green water. The salt System will not clear the water by It self. **Q: Is the sale price for 12 packs of the 1 lb shock, 6 packs or just each 1 lb item?** A: You receive 12 one pound packs. **Q: Is this good for vinyl pools?** A: Use Leslie's Chlor-Brite for long term pool maintenance. Pow Pow is strong enough to kill algae, but may ruin vinyl pools. You may use Pow Pow a few times a year for vinyl pool, but it is not recommended as it may ruin the vinyl lining. If you do use it, brush it around until it dissolves. I service pools for a living. ## Frequently Bought Together - Leslie's Power Powder Plus 73-73% Calcium Hypochlorite Pool Shock, Fast-Dissolving Chlorine Granules, Eliminates Bacteria & Algae - Low Residue, Non-Stabilized, 70% Available Chlorine - 12 x 1 Pound - Coral Seas Green Aid Green To Clean - 2 lbs. - Leslie's 3 Inch Stabilized Chlorine Tablets for Sanitizing Swimming Pools - Individually Wrapped, Slow Dissolving - 90% Available Chlorine - 99% Tri-Chlor - 10 Pounds --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.hk/products/316425977-power-powder-plus-73-73-cal-hypo-pool-shock-12](https://www.desertcart.hk/products/316425977-power-powder-plus-73-73-cal-hypo-pool-shock-12) --- *Product available on Desertcart Hong Kong* *Store origin: HK* *Last updated: 2026-10-02*
