How to Safely Lower Chlorine Levels in Your Hot Tub
Share
High chlorine levels in your hot tub can lead to skin irritation, a strong chemical smell, and discomfort during your soak. Thankfully, reducing chlorine levels is straightforward with the right steps and tools. Here’s how to lower chlorine levels safely and effectively.
Why Are Chlorine Levels Important?
Chlorine is an essential sanitizer for keeping your hot tub water clean and safe by killing bacteria and other contaminants. However, levels that are too high can create an unpleasant spa experience. Maintaining the ideal chlorine range of 1–3 ppm ensures safety and comfort for bathers.
How to Test Chlorine Levels
Before adjusting chlorine levels, it’s important to know your current readings. Use a test kit or test strips to measure the chlorine levels in your hot tub water. Make sure to follow the instructions on the testing product for accurate results.
Steps to Lower Chlorine Levels
1. Dilute the Water
If chlorine levels are only slightly high, try adding fresh water to the hot tub. Turn off the jets and drain a portion of the water, then refill with clean water. Retest to ensure the chlorine level has dropped to the desired range.
2. Leave the Cover Off
Chlorine naturally dissipates over time when exposed to sunlight and fresh air. Leave your hot tub uncovered for several hours to allow the chlorine to off-gas. Avoid direct sunlight if you’re concerned about temperature loss.
3. Use a Neutralizer
If chlorine levels are significantly high, a chlorine neutralizer like sodium thiosulfate can quickly bring them down. Be cautious and follow the manufacturer’s instructions to avoid over-correcting.
4. Turn on the Jets
Running the jets without adding more sanitizer can help distribute and dilute the chlorine levels throughout the water, speeding up dissipation. Combine this step with leaving the cover off for best results.
Tips to Avoid High Chlorine Levels
- Measure Carefully: Always follow dosing instructions for chlorine to prevent overuse.
- Use Alternative Sanitizers: Consider combining chlorine with bromine or switching to a system that requires less frequent adjustments.
- Test Regularly: Frequent testing ensures you catch high chlorine levels early, reducing the need for large adjustments.
When to Drain and Refill
If your chlorine levels remain too high despite these steps, it might be time to drain and refill your hot tub. This approach resets your water chemistry, making it easier to maintain balanced levels moving forward.
