Maintaining a clean and healthy hot tub requires more than just warm water and relaxation—it needs proper sanitization. Chlorine granules are one of the most effective and convenient ways to keep your hot tub water crystal clear and free from bacteria. However, using them correctly is key to achieving the best results and avoiding water imbalance or irritation. Here’s a step-by-step guide to help you use chlorine granules the right way.
Step 1: Test Your Water
Before adding chlorine, always test your hot tub water using test strips or a digital tester. This will help you determine the current chlorine level, pH, and alkalinity. Ideally, your chlorine level should be between 1–3 ppm (parts per million), while the pH should range from 7.2 to 7.6. Testing ensures you know exactly how much chlorine to add without overdoing it.
Step 2: Measure the Correct Amount
Chlorine granules are powerful, so a little goes a long way. The general rule is to use about one teaspoon of granules per 500 liters of water, but always check the product instructions for the recommended dosage. Using too much chlorine can make the water harsh on your skin and damage the hot tub components, while too little can leave bacteria behind.
Step 3: Dissolve the Granules (Optional but Recommended)
Although some chlorine granules can be added directly to the hot tub, pre-dissolving them in a clean bucket of warm water helps distribute the sanitizer more evenly. Stir the solution until the granules are fully dissolved. This prevents any granules from settling at the bottom of the tub, which could cause staining or surface damage.
Step 4: Add the Chlorine Solution
Slowly pour the dissolved chlorine mixture around the edges of the hot tub while the jets are running. The circulation will help spread the sanitizer evenly throughout the water. Let the water circulate for about 15–20 minutes before testing the chlorine levels again to make sure they’re within the safe range.
Step 5: Allow Time Before Soaking
After adding chlorine, it’s important to wait until the chlorine levels drop back to the recommended 1–3 ppm range. This usually takes around 30 minutes to an hour. Entering the hot tub too soon can cause skin or eye irritation, so patience is key.
Step 6: Maintain Regular Chlorination
To keep your hot tub clean and safe, maintain chlorine levels regularly. Test the water before each use and after heavy usage. A consistent routine will prevent cloudy water, unpleasant odors, and harmful bacteria buildup.
By following these simple steps, you can enjoy your hot tub with peace of mind, knowing it’s properly sanitized and ready for relaxation.
