Sanitiser: This helps to kill bacteria and other microorganisms that can build up in the water. Chlorine and bromine are the most common types of sanitiser used in hot tubs.

pH balancer: Hot tub water should have a pH level between 7.2 and 7.8. If the pH is too low, the water can become acidic and irritate the skin and eyes. If the pH is too high, the water can become basic and cause the sanitiser to be less effective. You can use pH plus or pH minus and adjust the pH to the proper range.

No-foam: This chemical helps reduce the amount of foam that can sometimes form in hot tub water. 

A sanitiser is essential for killing harmful microorganisms in the hot tub water. Chlorine and bromine are the most common sanitisers, and the recommended sanitiser level is 3-5 ppm (parts per million).

The pH level of hot tub water should be between 7.2 and 7.8. A pH adjuster, such as sodium carbonate or sodium bisulfate, is needed to maintain the proper pH level.

Both chlorine and bromine are commonly used as sanitisers in hot tubs to kill bacteria and other contaminants. The choice between the two often comes down to personal preference, as both have their benefits and drawbacks.
Chlorine is a strong and effective sanitiser that is widely available and relatively inexpensive. It is easy to use and can be added directly to the hot tub water in the form of tablets or granules. However, it can have a strong, unpleasant smell and can cause eye and skin irritation in some people. Chemicals for hot tub maintenance

Bromine is another effective sanitiser that is often used in hot tubs. It is less harsh than chlorine, has a milder smell, and is less likely to cause eye and skin irritation. However, it is more expensive than chlorine.

Ultimately, choosing chlorine and bromine for your hot tub will depend on your preferences and budget. It is essential to regularly test and maintain the proper levels of sanitiser in your hot tub to ensure clean and safe water for all users.

The recommended total alkalinity level in a hot tub is between 80 and 120 ppm. An alkalinity adjuster, such as sodium bicarbonate, is needed to maintain the proper total alkalinity level.

Shocking the hot tub water is important to eliminate organic matter and contaminants. Shock treatment should be done on a weekly basis or after heavy use. Both chlorine and non-chlorine shock can be used.

Stain and scale control products, such as sequestering agents, are used to prevent stains and scale build-up caused by minerals in the hot tub water.
