Chlorine is the most commonly used water treatment chemical and can kill most bacteria, viruses, and algae. Common chlorine sources in swim spa hot tubs include: • Liquid chlorine • Chlorine tablets or granules

Modern people often experience muscle stiffness, neck and shoulder pain due to prolonged sitting, lack of exercise, or excessive stress. The massage effect of the hot tub's water jets relaxes muscles and relieves lactic acid buildup, thereby reducing body tension and making the process of falling asleep more natural.

For example: • Using untreated hard water can lead to scale buildup, clogging nozzles and pipes; • Neglecting water balance can corrode the inner tank and electric heating system; • Failure to replace the filter for a long time can allow bacteria to grow, reducing the spa's effectiveness.

If your spa hot tub has the following characteristics, it is not recommended to use it as a shower: • The bathtub is made of thin acrylic walls, which are not suitable for standing; • It lacks an anti-slip bottom or safety handles; • Electrical components are exposed or close to the shower head area;

The water temperature in a regular bathtub gradually decreases, while a spa hot tub is equipped with a constant temperature heater, maintaining a constant temperature. This means the body's sweating response lasts longer, resulting in greater water loss.

Most spa hot tubs are equipped with electric heaters or heat pumps, using a temperature sensor to monitor the water temperature in real time. When the water temperature drops below the set value, the system automatically heats up; once the target temperature is reached, heating stops to maintain a stable temperature.
