Hot tubs are a popular way to relax and unwind after a long day, but it's important to maintain proper water chemistry to ensure a safe and enjoyable experience. Hot tub chemicals play a critical role in keeping the water clean and safe for use. In this blog, we will explore the different types of hot tub chemicals and their functions.
Chlorine - Chlorine is a common hot tub chemical used to sanitize water by killing bacteria and other contaminants. It comes in granular or tablet form and is added directly to the water or through a chlorinator. The ideal chlorine level for hot tubs is between 3-5 parts per million (ppm). However, excessive chlorine levels can cause skin and eye irritation, and a strong odour. Regular testing and adjustment of chlorine levels are essential to maintain a safe and comfortable hot tub experience.
Bromine - Bromine is another popular hot tub chemical used for water sanitation. It is more stable than chlorine and works better in warm water environments. Bromine is available in tablet or granular form and is added directly to the water or through a brominator. The ideal bromine level for hot tubs is between 3-5 ppm. Like chlorine, excessive bromine levels can cause skin and eye irritation, and a strong odour. Regular testing and adjustment of bromine levels are essential for maintaining a safe and comfortable hot tub experience.
pH Adjusters - The pH level of hot tub water is critical to maintaining proper water chemistry. The ideal pH range for hot tubs is between 7.2-7.8. If the pH level is too low, the water is too acidic, which can cause skin and eye irritation and damage hot tub components. If the pH level is too high, the water is too alkaline, which can lead to cloudy water and scaling. pH adjusters, such as pH plus and pH minus, are used to maintain the ideal pH range. These chemicals should be added in small increments to avoid overcorrecting and causing further imbalances.
Alkalinity Adjusters - Alkalinity adjusters are used to maintain the ideal total alkalinity (TA) level of hot tub water, which is between 80-120 ppm. Total alkalinity measures the ability of the water to resist changes in pH levels. If the TA level is too low, the pH level can fluctuate and cause damage to hot tub components. If the TA level is too high, the water can become cloudy, and scaling can occur. Sodium bicarbonate or alkalinity increaser is used to increase TA levels, while muriatic acid or alkalinity decreaser is used to decrease TA levels.
Calcium Hardness Adjusters - Calcium hardness is the measure of dissolved calcium in the water. The ideal calcium hardness range for hot tubs is between 150-250 ppm. If the calcium hardness level is too low, the water can become corrosive and damage hot tub components. If the calcium hardness level is too high, the water can become cloudy, and scaling can occur. Calcium increaser or hardness increaser is used to increase calcium hardness levels, while a product like calcium reducer is used to decrease calcium hardness levels.
In conclusion, hot tub chemicals are a critical component of maintaining a safe and enjoyable hot tub experience. Chlorine and bromine are used to sanitize the water, while pH adjusters, alkalinity adjusters, and calcium hardness adjusters are used to maintain proper water chemistry. Regular testing and adjustment of hot tub chemicals are essential to ensure the safety and comfort of hot tub users. It is important to follow the manufacturer's instructions when using hot tub chemicals and to use them in the correct amounts to avoid overcorrection and further imbalances.
