## Description

Leslie's Power Powder Plus 73 is the strongest chlorine pool shock available, designed to keep your pool water crystal clear and safe. With 73% Calcium Hypochlorite and a minimum of 70% available chlorine, this concentrated granular shock effectively kills bacteria, controls algae, and eliminates organic contaminants. It's ideal for both super chlorination and routine maintenance, providing a fast-acting solution for a wide range of pool problems. Power Powder Plus 73 dissolves quickly and leaves minimal residue, ensuring thorough sanitization without significantly increasing calcium hardness levels in your pool water. As a non-stabilized chlorine shock, it contains no cyanuric acid, meaning it won’t raise stabilizer levels, making it perfect for evening use to reduce UV degradation. Whether you’re dealing with a severe algae bloom or just need a routine chlorine boost, Leslie's Power Powder Plus 73 is your go-to solution for maintaining a clean and healthy swimming environment. Add 9-18 oz. per 10,000 gallons for super chlorination or 3 oz. per 10,000 gallons for routine maintenance to achieve 5-10 ppm available chlorine. Safe for use in all pool types, this powerful pool shock is an essential tool in your pool care arsenal.

Review: Excellent after Arizona dust storms - We have been using this product for years! Tried a different product to save money, but ended up with a terrible algae problem! This product along with another got the pool back in shape! I was purchasing this locally, however it was more expensive at the brick and mortar Leslie's. It's a better price here and it's delivered to your door!!! That's a win win for me. No more lugging it home and a better price point.
Review: Shock - Good product Purchase price less than in store

## Questions & Answers

**Q: Thank you, My pool was clear before I put this in. that stuff doesn't dissolve. 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.
