And what is the best way to go about doing it? In this post, we will answer those questions and more. So keep reading for all the info you need on changing your hot tub water!
How often should you change hot tub water?

Every hot tub owner knows that it is important to change the water regularly. But how often should you change hot tub water? The answer may surprise you. Experts recommend changing the water at least once every month. While this may seem like a chore, it is necessary to maintain a clean and healthy environment.
Every time you use the hot tub, contaminants from your body, including sweat, skin cells, and hair, are transferred into the water. Over time, these contaminants can build up, leading to an unhealthy environment. By changing the water every three months, you can flush out these contaminants and start fresh.
In addition, be sure to empty and clean the filter every time you drain the water.
Does a large hot tub need to be emptied less often than a small hot tub?
No, a large hot tub does not need to be emptied less often than a small hot tub. It is recommended that you empty your hot tub at least once a week, no matter the size. The reason for this is that hot tubs can become breeding grounds for bacteria and other microorganisms. When these organisms build up in the water, they can cause skin irritation, respiratory problems, and even gastrointestinal illness.
To prevent these health risks, it is important to keep your hot tub clean and free of contaminants. While emptying and refilling your hot tub may seem like a hassle, it is a necessary part of hot tub maintenance. By following this recommendation, you can help ensure that your hot tub is safe and enjoyable for everyone.
Reasons to regularly empty your hot tub
1. You can clear a build-up of body oils and biofilm
When you do not use your hot tub for a while, the water can start to become murky and green. This is because the body oils and sweat from previous users start to build up, as well as a substance called biofilm. Biofilm is made up of bacteria and other microorganisms that can be harmful to your health. Fortunately, there are some easy steps you can take to clear a build-up of body oils and biofilm.
The first step is to empty the hot tub and give it a good cleaning. You can use a mild detergent and a soft brush to scrub away any dirt or grime. Once the hot tub is clean, fill it up with fresh water and add some chlorine tablets. This will help kill any remaining bacteria and prevent further build-up. Finally, make sure you empty the hot tub and clean it regularly to prevent this problem from happening again in the future.
2. You can refresh your hot tub chemicals

As any hot tub owner knows, keeping the water clean and safe to use is essential. Part of this process involves regularly refreshing the hot tub chemicals in the water. Chlorine is the most common hot tub chemical, and it helps to kill bacteria and viruses. However, over time, chlorine levels can drop, making the water less effective at preventing illness. For this reason, it is important to test the chlorine levels in your hot tub regularly and add more chlorine as needed.
Another important hot tub chemical is pH Balancer. This chemical helps to maintain the pH level of the water, which should be between 7.2 and 7.6. If the pH level gets too high or too low, it can cause skin irritation and make the water less effective at killing bacteria. Therefore, it is important to add pH Balancer to your hot tub regularly as well. By refreshing your hot tub chemicals regularly, you can help ensure that your hot tub is always clean and safe to use.
3. You can clean out hot tub filters and jets
Most hot tubs have one or more filters that help to keep the water clean. Over time, these filters can become clogged with dirt and debris, reducing their efficiency. Fortunately, hot tub filters are designed to be easily removed and cleaned. The exact method will vary depending on the type of filter, but in general, you will need to remove the filter from the hot tub and rinse it with a hose. Once the filter is clean, you can put it back in place and enjoy the peace of mind that comes with knowing your hot tub is running at peak performance.
Similarly, it's not uncommon for hot tub jets to become clogged with dirt, soap scum, and other debris. If left uncleaned, this can lead to reduced water flow and poor jet performance. Fortunately, cleaning out hot tub jets is a relatively simple process. Start by turning off the power to the hot tub and removing the jet covers. Then, use a soft brush or cloth to remove any loose debris from the jet openings.
Next, fill a bucket with a mixture of warm water and white vinegar. Using a small brush, scrub the jets with the vinegar solution, being careful not to damage the finish. Once the jets are clean, rinse them thoroughly with fresh water and reattach the jet covers. With just a little bit of effort, you can keep your hot tub jets clean and operating at peak performance.
4. You can give the hot tub shell a deep clean

You can give the hot tub shell a deep clean with vinegar. Vinegar is an effective cleaning agent that can remove dirt, grime, and other debris from the surfaces of your hot tub. In addition, vinegar is also a natural disinfectant and can help to kill bacteria and fungi.
To use vinegar to clean your hot tub shell, simply mix one part vinegar with two parts water in a bucket. Then, use a sponge or cloth to apply the mixture to the surfaces of your hot tub. Allow the vinegar to sit for several minutes before rinsing it off with clean water. You may need to repeat this process several times to remove all of the dirt and grime from your hot tub shell.
5. You can identify any marks, scratches or dents in the hot tub
It is important to inspect your hot tub regularly for any damage that may have occurred. This is especially important if you have small children or pets, as they can easily scratch or dent the surface of the tub. If you do find any damage, it is important to repair it as soon as possible to prevent further damage from occurring.
The first step is to empty the tub and then clean the surface thoroughly. Once the surface is clean, you can inspect it for any marks, scratches or dents. If you find any damage, you can either repair it yourself or contact a professional for help. Either way, it is important to take care of any damage as soon as possible to keep your hot tub in top condition.
What happens if you don’t change your hot tub water?
As any hot tub owner knows, it is important to regularly change the water to maintain a clean and safe soaking environment. If the water is not changed regularly, it can become unclean and unsafe. Unclean water can harbour bacteria and other contaminants that can cause skin irritation and other health problems. In addition, unclean water can also lead to cloudy water and an unpleasant smell.
Not only does it remove contaminants from the water, but it also helps to maintain a pleasant smell. In addition, changing the water regularly also helps to extend the life of the hot tub and can clear unwanted foam that can build up from surfactants, spilt drinks and more.
Conclusion
In conclusion, it is important to change the hot tub water regularly to maintain a clean and safe environment. The general rule of thumb is to change the water every three months. However, this may vary depending on how often the hot tub is used. Be sure to consult your owner’s manual for specific guidance. By following these simple tips, you can ensure that your hot tub is always clean and safe for use.
