Description
Welcome to the world of Deep Blue Professional Stabilised Chlorine Granules 25kg! Dive into a realm of pristine pool and spa water that sparkles with cleanliness and safety. Our chlorine granules are a must-have for maintaining a hygienic aquatic environment free from harmful bacteria.
Designed for both hot tubs and swimming pools, these granules rapidly dissolve to deliver a neutral pH balance, ensuring your water remains crystal clear and inviting. With a long-lasting formula, you can trust in the efficacy of these stabilised chlorine granules to keep your pool or spa in top condition.
One of the standout features of our granules is their minimal impact on the pH level of the water, making them an ideal choice for regular dosing. By producing free active chlorine, these granules work tirelessly to eliminate bacteria and other potential contaminants, giving you peace of mind as you enjoy your aquatic oasis.
For optimal results, it is recommended to maintain the pH level within the range of 7.2 to 7.6. Should adjustments be necessary, our PH plus or PH minus products are available to help you achieve the perfect balance for your pool or spa.
When it comes to dosing, our application instructions provide clear guidance on how to use the granules effectively. Whether you’re treating a hot tub or a swimming pool, ensuring the free chlorine residuals fall within the specified ranges is key to a healthy water environment.
For newly filled spas, an initial shock or start-up dose is essential to kickstart the sanitization process. By following our recommended dosing rates and application methods, you can maintain optimal chlorine levels and ensure that your pool or spa remains a safe and enjoyable space for relaxation.
Our granules can be applied directly to pools or spas, particularly in warmer temperatures exceeding 20 degrees Celsius. In cases where the temperature is lower, pre-dissolving the granules in water before adding them to the water body is advised to ensure proper dispersion and effectiveness.
Regular maintenance is key to the longevity of your pool or spa. Periodically shock dosing your spa, especially after heavy use, helps eliminate any accumulated contamination and keeps the water fresh and inviting.
With dose rates provided for various water capacities, from medium hot tubs to large pools, you can easily calculate the right amount of granules needed to achieve the desired chlorine levels. Our granules offer a convenient and efficient way to ensure your water is always in top condition.
Experience the power of Deep Blue Professional Stabilised Chlorine Granules 25kg and elevate your pool and spa maintenance routine to new heights of cleanliness and clarity. Trust in the quality and effectiveness of our granules to keep your aquatic haven pristine and inviting for all your water activities!
