Hot tubs are a great way to relax in your own home, but it’s important to keep the water in the tub clean, clear and safe by properly maintaining it. Maintaining hot tub water is a vital part of enjoying and getting the most out of your hot tub and avoiding potential health issues. Here, we will discuss the steps you need to take to maintain and care for your hot tub’s water.
1. Test the Water
Test the pH Level
Testing the pH level of the water in the hot tub is a critical step in maintaining the water. The ideal pH range is between 7.2 and 7.8. To test the pH level of your hot tub water, you need to buy a single test strip from a pool or hot tub supply store. Any readings outside this range can affect the hot tub’s water chemistry and damage the equipment.
Test for Total Alkalinity
The total alkalinity of the water in your hot tub should range from 80 to 150 ppm. This can be tested using the same type of test strip that is used for pH levels. If the total alkalinity in the water is below 80 ppm or above 150 ppm, the organic and inorganic products are likely to change the water chemistry, resulting in scale buildup and damaging the circulation system.
2. Sanitize the Water
Add Chlorine to Disinfect the Water
Chlorine is often used to kill bacteria, algae, and other organisms that should not be in the water. Adding the right amount of chlorine can kill the organisms and help to prevent future growth. Adding too much chlorine, however, can be hazardous to your health. The chlorine level should be between 1.0 and 3.0 ppm.
Use Bromine for Sanitizing
Bromine is another sanitizer that can be used to disinfect hot tub water. The recommended level of bromine is between 2.0 and 4.0 ppm. It is also important to note that when bromine is used, the pH level of the water should be between 7.4 and 7.6.
3. Shock Treat the Water
Regular Shock Treatments
Regular shock treatments are necessary for the continued maintenance of your hot tub. Shock treatments help to break down by-products in the water and ensure that it remains clean and clear. The recommended amount of shock to use is 1 pound of shock per 500 gallons of water, and it should be applied at least once every 3 weeks.
Shock Treat After Heavy Use
If your hot tub is in heavy use, you may need to increase the frequency of your shock treatments. Shock treatments help to break down the organic material in the water, which will help to prevent any potential buildup of bacteria or algae. You can use the same amount of shock treatment as you would when treating a light use hot tub – 1 pound per 500 gallons.
4. Balancing the Water
Balance the pH Level
The pH level of the water needs to be balanced in order to ensure that the water is healthy. To adjust the pH level, you can use a pH balancer, which is available at most pool and hot tub supply stores. This product should be added according to the directions on the package, as the amount you need to add will vary depending on the size of your hot tub.
Add Hardness Increaser
If you find that the hardness of the water in your hot tub is too low, you can use a hardness increaser to raise the level. Hardness increasers are available from most pool and hot tub supply stores, and you should follow the directions on the package in order to achieve the desired results.
5. Clean the Filter
Backwash the Filter
The filter in your hot tub needs to be cleaned regularly in order to keep the water clean and clear. This can be done by backwashing the filter. To do this, turn on the backwash setting and let the filter run for 5 to 10 minutes. This will allow the filter to break down the impurities and prevent them from building up in the water.
Replace the Filter
In addition to backwashing the filter, you may also need to replace it if it becomes too clogged. The filter may need to be replaced every 3 to 6 months, depending on the use. Replacing the filter is the best way to ensure that your hot tub is working properly and that the water is not contaminated.
6. Change Filter Media
Activated carbon is an effective filter media for hot tubs. It helps to reduce the levels of chlorine and contaminants in the water. Activated carbon should be changed every 2 to 6 weeks, depending on your hot tub usage.
Zeolite media is another effective filter media that can be used in hot tubs. This media helps to reduce the levels of hydrogen sulfide and ammonia in the water. It can absorb small particles and help to keep the water sparkling clean. Zeolite media should be changed every 2 to 4 weeks.
7. Prevent Leaks
Leaks in the hot tub can affect the water chemistry and cause a range of problems. It is important to check all connections regularly to ensure there are not any leaks in your hot tub. Inspect the pipes, hoses, and valves for any signs of leakage or damage. You can use a sealant to fix any leaks that are found.
Check for Cracks
It is also important to check for cracks or damage to the hot tub itself. The most common cause of cracks is age, but it is possible for the hot tub to be damaged by improper usage. If you do find a crack or damage, it is important to repair it immediately in order to prevent any further damage.
8. Monitor the Water
It is important to monitor the water in your hot tub regularly to ensure that it is clean and safe. The total alkalinity, pH level, and chlorine should be tested regularly and the filter should be inspected and cleaned as needed. Additionally, the hot tub should be emptied and the filter replaced periodically.
People Also Ask
How Often Should You Clean a Hot Tub Filter?
The frequency of cleaning a hot tub filter depends on how often the hot tub is used. If it is used frequently, the filter should be cleaned once a month. If the hot tub is not used often, the filter should be cleaned at least every 3 months.
What Can You Use to Clean the Hot Tub?
A mild solution of water and dish soap can be used to clean the walls and steps of a hot tub. It is important to avoid using abrasive cleaners, as they can damage the surface of the hot tub.
How Long Should You Run the Hot Tub After Adding Chemicals?
It is recommended that you wait at least 15 minutes after adding chlorine or other chemicals to the water before using the hot tub. This gives the chemicals enough time to dissolve and reach an appropriate level in the water.
Should You Add Chemicals After Each Use?
It is not necessary to add chemicals to the water after each use. You should, however, test the water levels on a regular basis and add chemicals as needed in order to keep the water balanced and safe.
Maintaining hot tub water is an important part of the hot tub experience. Properly maintaining the water not only makes it healthier, but also extends the life of the hot tub. By following the steps outlined above, you can keep your hot tub’s water clean, safe, and balanced.
