When the alkalinity in a hot tub is too high, one of the most obvious consequences is the buildup of scale. Scale is a deposit formed by the reaction of minerals in the water, especially hardness components such as calcium and magnesium, with carbonates and bicarbonates.

The maximum water temperature of modern hot tubs is usually set at 104°F (40°C), which is the internationally recognized safety upper limit. Most hot tub temperature control systems will force the water temperature to not exceed this standard.

Advantages of long-term opening ● Maintaining massage effect: Turning on the relaxation nozzle for a long time can maintain continuous water flow massage, help relieve muscle tension, and bring a deeper relaxation effect. ● Good water circulation effect: The long-term opening of the nozzle helps the water body circulate, which can prevent the water quality from becoming turbid, and at the same time allow the disinfectant to be fully distributed in the water.

we can roughly determine the nozzle configuration plan for a 4-person outdoor hot tub. For an ordinary 4-person bathtub, it is usually necessary to configure 12 to 20 massage nozzles.

For a 10-jet system, the total impact force is 7.56 Newtons. This is the total pressure exerted by the water flow on the surface of the human body. Although this number may seem small, in actual use, it will be significantly amplified due to the distribution of the water flow and the different contact areas of the human body, producing a massage effect.

When the pH level in a hot tub is too low, the water becomes acidic, which can have significant effects on the skin. Acidic water weakens the natural barrier on the surface of the skin, making the skin more vulnerable to chemicals and bacteria, which can cause problems such as rashes.

Hot tubs are typically set at a maximum temperature of 104 degrees Fahrenheit, which is the upper safety limit set by the U.S. Consumer Product Safety Commission (CPSC) and many hot tub manufacturers.

Generally speaking, the higher the horsepower, the greater the water flow and pressure, which can provide a stronger massage effect. In hot tubs, the horsepower of the water pump usually ranges from 1.5 HP to 3 HP, and can even reach 4 HP or more in some large hot tubs.

One of the biggest advantages of swim spas is that they can bring swimming and hydrotherapy into family life. Swim spas installed at home can be used at any time without going out or making an appointment. Users only need to enjoy high-quality water sports and relaxation experiences at home.

Studies have shown that soaking in a hot tub for an hour may burn the same calories as taking a walk or doing a low-intensity exercise. This means that while hot tubs are not a replacement for exercise, they can certainly be used as an aid to weight loss, especially for those who are physically unable to engage in vigorous exercise, as hot tubs offer a low-impact, stress-free way to burn calories.

For example, an adult over 1.75 meters tall may need a soaking depth of 45 cm or more to ensure that the shoulders are covered by water. For people under 1.60 meters tall, a soaking depth of about 40 centimeters is comfortable enough.

Advantages of bromine: Stable under high temperature conditions Less irritating Continuous sterilization ability Bromine has certain disinfection ability Not susceptible to pH fluctuations Disadvantages of Bromine: Higher cost Not as oxidizing as chlorine Bromine accumulation problem Requires regular maintenance and replenishment Compatibility with devices
