Calcium chloride is a powerful tool for maintaining your swimming pool's water balance, particularly for increasing calcium hardness. However, its effective use relies on understanding proper handling and application methods. NINGBO INNO PHARMCHEM CO.,LTD. is dedicated to providing not only quality chemicals but also the knowledge to use them safely and effectively.

When increasing your pool's calcium hardness, particularly if you are aiming for the ideal range of 200-400 ppm, calcium chloride is often the preferred choice. It's important to know that calcium chloride releases heat when it dissolves in water. Therefore, the most critical safety and efficacy tip is to always pre-dissolve calcium chloride in a bucket of pool water before adding it to the pool. Never add the dry chemical directly into the skimmer or pour it into the pool without dissolving it first. This can lead to concentrated hot spots that can damage your pool surfaces, particularly vinyl liners or plaster.

To safely use calcium chloride, you will need a clean bucket, pool water, and the calcium chloride product. Measure the required amount of calcium chloride based on your pool's volume and the desired hardness increase. A general guideline is to add about 1 to 1.25 pounds of calcium chloride per 10,000 gallons of water to raise the hardness by 10 ppm. Slowly add the calcium chloride to the bucket of water while stirring. Avoid adding too much at once, and be mindful of the heat generated. Some recommend adding a chelating agent like SC-1000 to help the calcium stay dissolved and prevent precipitation. Once fully dissolved and the solution has cooled slightly, slowly pour it around the perimeter of the pool while the pump is running.

Understanding the impact of low calcium hardness on pool equipment underscores the importance of correct application. Corrosive water can leach calcium from surfaces, leading to etching and damage. By using calcium chloride correctly, you are actively preventing these issues. For those seeking reliable products, NINGBO INNO PHARMCHEM CO.,LTD. offers high-grade calcium chloride that ensures consistent results. Always follow product instructions and safety guidelines to ensure a safe and effective pool season. Proper application is key to benefiting from calcium chloride for swimming pool health.
