BWT Calcium Hypochlorite Granules - 5 kg Bucket - Shock Treatment for Swimming Pools

Technical Specifications for BWT Granular Calcium Hypochlorite

BWT calcium hypochlorite granules are a concentrated formula for oxygenation and shock disinfection, designed for regular or corrective maintenance of pool water.

Its powerful action destroys microorganisms without saturating the water with stabilizer residues, thereby preserving the overall disinfecting power of your filtration system.

Chemical Properties and Prevention of Over-Stabilization

The use of unstabilized chlorine based on pure calcium hypochlorite offers a major technical advantage for private swimming pools: it does not inhibit the action of chlorine. .

Conventional chlorine products contain isocyanuric acid, which accumulates and eventually saturates the water, rendering treatments ineffective and requiring the pool to be drained. .

This BWT granule partially overcomes this drawback by releasing pure, volatile active chlorine, which is ideal for destroying algae and rapidly clarifying the water. .

It is recommended to maintain an optimal chlorine level between 0.4 and 1.4 mg/L for long-term chlorination, and to keep the stabilizer level below the recommended value of 35 mg/L. .

Instructions for Use and Safety Precautions

To use this chemical effectively and safely in your pool, follow these instructions: .

• Step 1: It is best to dissolve the granules in a bucket of clean water before distributing the solution evenly over the pool surface or in front of the return jets. .

• Step 2: Do not pour the product directly into the pool skimmer if it already contains other types of stabilized chlorine (tablets), to avoid any dangerous chemical reactions. .

• Hazards: Hazard statement: May intensify a fire (oxidizer). . Harmful if swallowed. . Causes severe skin burns and serious eye damage. . Very toxic to aquatic life. .

• Protection: Always wear protective gloves, protective clothing, and eye and face protection whenever handling this product. .

• Storage: Keep the container tightly closed in a cool, dry, and well-ventilated area, away from direct light, heat, and combustible materials. .
