- Residential swimming pool maintenance
Understanding Calcium Hypochlorite
Calcium hypochlorite, commonly called Cal-Hypo, is an unstabilized chlorine compound used to sanitize swimming pool water. Unlike stabilized chlorine products, calcium hypochlorite does not introduce cyanuric acid into the swimming pool.
However, Cal-Hypo does contribute calcium to the water. Pool owners should monitor calcium hardness, pH, free chlorine, and other water balance parameters when using calcium hypochlorite products.
Calcium hypochlorite may also cause temporary water cloudiness or leave residue under certain water chemistry conditions, particularly when calcium hardness or pH is elevated.
Application and Pool Water Maintenance
Always follow the manufacturer's product label for the correct treatment dosage, application method, circulation requirements, and swimming restrictions.
Before treatment, test swimming pool water to determine the current free chlorine level, pH, calcium hardness, and other relevant water chemistry parameters. Use the labeled dosage appropriate for the swimming pool's water volume and treatment requirements.
Maintain proper pool circulation and filtration during treatment as directed by the product label. Retest the swimming pool water before allowing swimmers to enter.
Pool Chemical Safety and Storage
- Read and follow all product label instructions and warnings before use.
- Never mix calcium hypochlorite with other pool chemicals, including stabilized chlorine, acids, or other shock products.
- Never add water to the chemical container.
- Use only the application method specified on the product label.
- Store in the original container in a cool, dry, well-ventilated area.
- Keep away from moisture, combustible materials, and incompatible chemicals.
- Use appropriate protective equipment when handling pool chemicals.
- Keep out of reach of children and pets.
