Hot Tub Water Chemistry 101
Spa water chemistry is not as complicated as it seems, but keeping it balanced is essential. Balanced water in your hot tub brings comfort to your skin and eyes and protects the hot tub shell and itself from damage.
Unbalanced water can lead to issues such as scale buildup or corrosion and can also become a breeding ground for unwanted microorganisms.
Regularly using the right hot tub chemicals and a good hot tub cleaner is crucial to keeping the hot tub clean and safe for use and ensuring the water remains balanced and sanitized.
Components of Water Chemistry
To achieve water balance, you need to maintain the right levels of pH, total alkalinity, and calcium hardness.
1. pH Level
pH measures how acidic or basic your water is on a scale from 0 to 14, with 7 being neutral. Your hot tub water should have a pH between 7.2 and 7.8.

Understanding Water Balance Interactions
The relationship between pH, alkalinity, and calcium hardness is key for maintaining balanced water:
- If the alkalinity is too high, it becomes challenging to adjust the pH.
- Low calcium hardness can cause corrosive water that damages hot tub components, while high calcium hardness leads to scale buildup.
Regularly testing all three elements together ensures the water remains stable, clear, and comfortable for use.
The Role of Sanitizers in Hot Tubs
Sanitizers are chemicals you add to your hot tub water to kill bacteria, viruses, algae, and other microorganisms, ensuring a safe and clean environment.
While hot tubs are the primary focus here, it's worth noting that sanitizers like bromine are also extensively used in swimming pools, showcasing their versatility.
In both hot tubs and swimming pools, bromine is effective in maintaining water quality and safety, though the ideal concentration varies slightly due to differences in temperature and usage patterns.
Common sanitizers include:
- Chlorine: Popular in both hot tubs and swimming pools, with an ideal concentration of 3.0 ppm in hot tubs. (Learn more here: Best Hot Tub Chlorine: Top 10 Options)
- Bromine: Especially effective in hot water, recommended to be maintained at 3.0 to 5.0 ppm in hot tubs, and slightly lower in swimming pools due to their cooler temperatures.
- Biguanide: An alternative to chlorine and bromine, suitable for those looking for a different method to sanitize their water, whether in hot tubs or pools, following specific guidelines for use.
Chlorine vs. Bromine: A Practical Comparison
- Chlorine is well-known for its rapid bacteria-killing properties, making it the go-to choice for many hot tub owners. It tends to dissipate faster in high temperatures and can produce a strong smell when it reacts with contaminants.
- Bromine remains more stable in hot water and is gentler on sensitive skin, though it requires a bromine feeder for consistent distribution.

Testing and Adjusting Chemical Levels
Maintaining the correct chemical balance in your hot tub is essential for ensuring the water is safe and comfortable. Regular testing and prompt adjustments can prevent skin irritation and equipment damage.
Frequency of Testing
You should regularly test your hot tub water at least twice a week. Frequent testing helps you stay ahead of potential imbalances.
Using Test Strips and Kits
To test your water, you'll need test strips, liquid test kits, or a digital hot tub water test kit. Dip the test strip into the water and compare the resulting colors with the chart provided.
For more precision, use a liquid test kit which involves adding a few drops of testing solution to a water sample.
Adjusting pH Levels
The pH level in your hot tub should be between 7.2 and 7.8. If it's too low, the water is acidic, and a pH increaser is needed. If it's too high, the water is basic, and a pH decreaser is your solution.
Add chemicals slowly and measure again after each adjustment.
Step-by-Step pH Adjustment Guide:
- Test the Water: Use test strips or a liquid kit to identify the current pH level.
- Calculate Adjustment: If the pH is below 7.2, use a pH increaser; if it's above 7.8, use a pH decreaser. Follow the product's dosage instructions based on your hot tub's water volume.
- Apply Chemicals Gradually: Add the pH adjuster slowly, circulating the water for 30 minutes.
- Retest the Water: After waiting, retest to ensure the pH has stabilized within the ideal range.
- Monitor for Fluctuations: Check the water again the next day to confirm the adjustment has taken effect.
Managing Total Alkalinity
Total Alkalinity (TA) acts as a buffer for pH levels. Keep TA between 80-120 ppm. If TA is low, add an alkalinity increaser. If it's too high, use a pH decreaser. Adjust slowly and retest.
Calcium Hardness Considerations
Calcium hardness should be in the range of 150-250 ppm to prevent damage to the tub and spa water cloudiness. If calcium hardness is low, add a calcium increaser. If it's high, dilute the tub water with fresh water or use a chemical reducer.

Sanitizing Your Hot Tub
Sanitizers are essential for killing bacteria and keeping your hot tub water clear. They play a crucial role in destroying organic contaminants, ensuring the water remains clean and safe for use.
Two main types are common: chlorine and bromine. You can choose based on your preferences and needs.
Chlorine and Non-Chlorine Options
Chlorine is the most popular sanitizer because it's effective and cost-efficient. It comes in granules or tablets. Non-chlorine options like bromine are great if you have sensitive skin, as they're typically less irritating.
Understanding Sanitizer Levels
You need to check sanitizer levels regularly. Keep chlorine levels at 3 ppm and bromine levels at 3-5 ppm for a balanced hot tub.
- 3 ppm for chlorine
- 3-5 ppm for bromine
Lower than recommended levels of chlorine or bromine may fail to effectively kill bacteria and viruses, leading to the risk of waterborne illnesses.
Excessively high levels can cause skin and eye irritation, as well as potentially damage the hot tub's components over time.
A precise balance is essential: chlorine levels below 3 parts per million (ppm) might not properly disinfect the water, while levels above this can lead to harsh chemical odors and discomfort for users.
Shocking the Hot Tub
Shocking your hot tub means adding a large dose of sanitizer to destroy contaminants. You should do this once a week or after heavy use.
You can use chlorine shock, a strong and fast-acting type, or non-chlorine shock, which is gentler and good for regular maintenance.
