You should put chlorine in your hot tub at least once a week. However, some people prefer to add a small amount after each use. Finding the best water care routine will depend on how often and how many people use it. Chlorine levels should be between 1.5 and 3.0 ppm.
Your hot tub will need to be treated with a Sanitiser to control and prevent bacteria growth. Bacteria can multiply rapidly in a hot environment, so you must maintain an appropriate sanitiser level to ensure any bacteria in the water is killed.
Add Spa shock (100 grams / 4 Capfuls) at least once a week, twice if the spa is used frequently or you have a large number of people using the hot tub. Spa Shock breaks down organic material in the water that can cause bad odors and cloudy water. Spa Shock works together with Sun-Boom to maintain water clarity.
Regular hot tub shocking is inevitable to keep your water clean and safe for use. Dead skin and other elements like hair may end up dropping in the hot tub, leaving the tub in a mess. It is essential to shock the hot tub frequently – at least once every week.
Chlorine works faster to kill contaminants but for a shorter period of time, as it dissipates faster. Bromine kills contaminants more slowly but for a longer period of time; plus, it can help keep water chemistry more balanced due to its low pH, meaning less chemical adjusting is needed.
How Much Bromine to Put in A Hot Tub. You should ensure that your hot tub bromine level is always between 3-5ppm (parts per million. The addition of bromine will depend upon usage and bathing habits. It could be daily or every 2-3 days (for 3ppm add 12g per 1500 litres).
Chlorine – The most popular hot tub sanitiser, chlorine is fast acting and effective at killing bacteria. Our chlorine hot tub maintenance guide explains more about how chlorine works. Bromine – Ideal for those with sensitive skin, bromine reacts slower than chlorine and is effective at killing bacteria.
How much chlorine should I add to my hot tub? Aim to maintain a chlorine level of 3 to 5mg/l at all times. How frequently you add more chlorine will depend on your usage and bathing habits. It could be daily, every two to three days or weekly.
The chemicals you will need to start your hot tub include a pH increaser, pH decreaser, calcium hardness, a metal removal (if using water from rainwater tanks or bore) and a sanitiser.
Swim spa and hot tub owners who are struggling to keep the chlorine levels up might have an issue with biofilm. Biofilm is caused by bacteria or microorganisms that stick themselves to a surface that is in contact with water. Resistant to chlorine, biofilm will cause the chlorine to “disappear” from your hot tub water.
You will have to drain as adding chlorine to your current tub will just convert the bromide back to bromine. The bromide will dissipate eventually but take an extremely long time to do so, so a water change now is the only way to quickly convert from bromine to chlorine.
Chlorine tablets are a great way for you to keep your hot tub, pool, or inflatable spa clean throughout the year. They are a great choice because they have the ability to sanitize algae, bacteria, and other contaminants while also being affordable.
Again, as a general rule of thumb, people should wait at least 30 minutes after adding chlorine before getting in the hot tub. Those who use bromine might have to wait a little while longer. Make sure the hot tub cover is off, allowing chemical vapors to escape.
With average use, your hot tub should be drained and refilled about once every three or four months. But since everyone uses their hot tub differently, the answer can vary based on how many people use it and how often. Hot tub manufacturers like Jacuzzi offer some handy tips for figuring out when to drain and refill.
When you add bromine to a chlorine pool, on the other hand, the bromine does not go away but builds up over time, creating a chlorine demand. Therefore, when you shock the pool with chlorine, the residual bromine will convert the chlorine into, you guessed it, bromine.
Switching from Chlorine to Bromine? To switch from chlorine to bromine, one simply needs to stop using chlorine tablets and begin using bromine tablets. If you use a tablet feeder or chlorinator, it should be replaced, so that chlorine residue does not come into contact with bromine, which could be dangerous.
Both chlorine and bromine are sanitizers that work in different ways to keep your water free of contaminants. Regular use of either chlorine or bromine will help keep your hot tub clean. The way they do it is different, but the results are similar.
If you have a spa, bromine has a lot of advantages over using chlorine. It may cost a little bit more, but it lasts longer and does a much better job than chlorine at killing bacteria, especially at high temperatures and high pH levels.
Bromine is a naturally occurring element that is a liquid at room temperature. It has a brownish-red color with a bleach-like odor, and it dissolves in water.
