Description
If you’re looking to maintain a safe and bacteria-free environment in your hot tub or swimming pool, the Deep Blue Professional Mini 20g STABILISED Chlorine Tablets are the perfect solution. These tablets are highly popular for their effectiveness in keeping water clean and clear, ensuring your water is always ready for a relaxing dip.
Designed to be stabilised to prevent chlorine loss to sunlight, these tablets offer a slow release of chlorine over 2-4 days, depending on the water flow. This slow and steady release mechanism ensures that your water remains consistently sanitized without any sudden fluctuations.
Whether you use floating dispensers, chemical feeds, or skimmer baskets, these chlorine tablets are versatile and easy to use. Simply apply them regularly to maintain the recommended free chlorine levels of 3-5 mg/l for hot tubs and 1-3 mg/l for swimming pools. Their slow-release formula ensures a long-lasting effect with minimal impact on the water’s pH balance.
The key features of these stabilised chlorine tablets include their ability to help you achieve the ideal free chlorine range for your hot tub or swimming pool. By producing free active chlorine that effectively eliminates bacteria and other harmful organisms, these tablets provide a high level of available chlorine and chlorine stabilizer for optimal water quality.
When it comes to application, following these instructions will help you make the most of your chlorine tablets:
1. Maintain the pH level within the range of 7.2-7.6, using pH plus or minus products if needed for adjustment.
2. Keep the free chlorine residuals within the recommended range for hot tubs and swimming pools. Freshly filled hot tubs may require an initial shock dose of chlorine to kickstart the sanitization process.
3. For floating dispensers, adjust the tablet quantity to achieve the desired chlorine level or regulate the dispenser’s aperture. Ensure the dispenser is removed while bathing.
4. Chlorine feeders should be filled according to the instructions to maintain the required chlorine levels consistently.
5. Skimmer baskets can be filled with tablets, but regular monitoring is necessary to ensure the chlorine levels are maintained as needed.
6. Periodically shock dosing your pool is recommended to eliminate any excess contamination and maintain water clarity.
Keep in mind the dose rates based on water flow rate and temperature to ensure the appropriate amount of tablets is used for your specific hot tub or swimming pool size.
By using the Deep Blue Professional Mini 20g STABILISED Chlorine Tablets with Floating dispenser, you can enjoy crystal-clear water that is safe and inviting for your family and friends. Trust in the reliability and effectiveness of these chlorine tablets to keep your water clean and healthy for all your aquatic adventures.
