In The Swim Chlorine and Shock Bundle for Sanitizing Swimming Pools – Includes 5 Pound Bucket of 3 Inch Stabilized Chlorine Tablets and 6 x 1 Pound Bags of 68% Cal-Hypo Pool Shock

Chlorine (3 Inch Tablets) is essential for a clear and healthy pool. Shock (Calcium Hypochlorite) rapidly raises chlorine levels while chlorine tabs maintain them. Both are necessary: shock ensures high enough chlorine levels for full sanitization and tabs prevent chlorine from dissipating. Shock the pool every 1-2 weeks more often in hot weather or with increased use. Replace tabs as needed.
