Bromine
Bromine is an alternative to chlorine for sanitizing pool water, and while it works similarly to chlorine by preventing the buildup of bacteria and algae, it has a few key differences. Bromine is odorless and tends to be less irritating to swimmers, making it a popular choice for those with sensitive skin or eyes. It’s highly effective at keeping the water clean and safe for swimming, especially in warmer temperatures, as bromine is more stable in high heat than chlorine.
Despite its benefits, bromine is still a chemical and should be handled with care. Always read the instructions on the container before use to ensure safe and proper application. When handling bromine, it’s important to wear protective gloves to avoid skin contact, as direct exposure can cause irritation. Ensure that you add the appropriate amount of bromine based on your pool’s size and needs. Overdosing the pool with bromine can lead to skin irritation for swimmers, so it’s essential to follow the recommended dosage and monitor the water quality regularly.
Bromine is available in several forms, including tablets, granules, and liquid. The most common forms are tablets, which can be placed in a floating dispenser or a skimmer. Consult your pool professional to determine the best bromine form and dosage for your pool.
Muriatic Acid
Muriatic acid, also known as hydrochloric acid, is commonly used in swimming pools to lower high pH levels. When the pH of your pool water exceeds 7.6, adding muriatic acid helps restore the balance. High pH levels can lead to scaling on pool surfaces and equipment, making the water uncomfortable for swimmers. Muriatic acid is a mild form of acid, making it safer for pool use, but it should still be handled with caution.
Before using muriatic acid, always purchase it from a reputable pool supply store and follow the manufacturer’s instructions carefully. It’s crucial to add only the recommended amount based on your pool’s specific needs. When handling muriatic acid, wear chemical-resistant gloves and safety goggles to protect your skin and eyes from potential burns. Never add water to acid, but always add acid to water, as mixing them incorrectly can cause a dangerous reaction. Once added to the pool, keep the filtration system running for several hours to allow the acid to circulate and lower the pH level effectively.
If you come into contact with muriatic acid, rinse the affected area with water for at least 15 minutes to prevent chemical burns. If irritation persists, seek medical attention immediately. Muriatic acid is available in liquid form and is typically sold in gallon containers for easy handling.
Calcium Chloride
Calcium chloride, often referred to as calcium increaser or hardness increaser, is a salt compound used to raise the calcium hardness level in pool water. It is typically added when test results show low calcium levels, which can lead to issues such as corrosion of pool equipment and etching of plaster or concrete pool surfaces. Adding calcium chloride helps to balance the water’s overall hardness, preventing these problems and ensuring the water is comfortable for swimmers.
When handling calcium chloride, it’s important to follow the instructions provided by your local pool professional and the product label carefully. Always add calcium chloride to water, not directly to the pool. First, fill a bucket with pool water, leaving about ¼ of the bucket empty, and then add the recommended amount of calcium chloride. Stir the mixture until the calcium chloride is completely dissolved. Once dissolved, slowly pour the solution around the perimeter of the pool to evenly distribute it. Avoid pouring undissolved calcium chloride into the pool as it can settle on the pool floor and leave unsightly stains.
Calcium chloride is typically available in granular or tablet form, and it is essential to use the correct amount based on your pool’s size and calcium level. Following proper handling and application procedures will ensure effective results and prevent damage to your pool surfaces.

Chlorine Stabilizer
Chlorine stabilizer, also known as cyanuric acid (CYA), is an essential chemical used to enhance the effectiveness of chlorine in your pool. One of chlorine’s main drawbacks is that it rapidly breaks down when exposed to the sun’s ultraviolet (UV) rays. This breakdown leads to reduced chlorine levels in the pool, which can compromise sanitation and allow bacteria and algae to flourish. By adding chlorine stabilizer to your pool, you help protect the chlorine from UV degradation, allowing it to last longer and maintain a consistent level of sanitization in the water.
Cyanuric acid is typically used when testing reveals low stabilizer levels, especially in outdoor pools that are exposed to direct sunlight. Maintaining the proper level of stabilizer ensures that chlorine remains effective over time, reducing the need for frequent chlorine additions. Cyanuric acid is available in granular or liquid form, with the granular version being more commonly used as it is easier to apply and dissolve in the pool.
When handling chlorine stabilizer, it’s important to follow all safety instructions provided by the manufacturer. Always add stabilizer to the pool slowly and avoid overuse, as too much cyanuric acid can lead to ineffective chlorine levels. Regular testing is necessary to ensure the stabilizer is within the recommended range of 30–50 ppm to optimize the chlorine’s performance.
Shock Treatments
Shock treatment is a powerful and quick method used to sanitize pool water by delivering a concentrated dose of chlorine or other disinfectants. This treatment is designed to break down organic contaminants, including sweat, oils, sunscreen, body fluids, and other impurities that can accumulate in the pool. Shock treatment is particularly effective in removing chloramines, which are compounds formed when chlorine combines with these impurities. By eliminating chloramines, shock treatment helps to restore water clarity, improve sanitizer efficiency, and maintain a healthy swimming environment.
There are different types of shock treatments available, with the most common being calcium hypochlorite, sodium dichloride, and potassium monopersulfate. Calcium hypochlorite and sodium dichloride are chlorine-based shocks, while potassium monopersulfate is a non-chlorine shock alternative. The choice of shock treatment depends on the specific needs of the pool and its water chemistry.
When performing a shock treatment, safety precautions are essential. Always wear protective gloves and goggles to prevent irritation, as the chemicals can be caustic. Follow the manufacturer’s instructions carefully regarding the correct dosage and application method. Shock treatment should be added in the evening or at night to prevent the sun from degrading the chemicals before they have a chance to work. It is also important to keep swimmers out of the pool until the shock treatment has been fully dispersed and the water’s chlorine levels return to safe ranges.
Algaecide
Algaecide is a chemical treatment used to prevent and control algae growth in swimming pools. It is not always necessary if the pool’s water chemistry is properly balanced, and the pH levels are maintained. However, algaecide is often used as a preventative measure or when algae blooms are present. Algae can thrive in pools with poor circulation, unbalanced water, or insufficient chlorine levels, turning the water cloudy or green and making the pool surface slippery. Algaecide works by inhibiting the growth of algae, helping to maintain a clear, clean, and safe swimming environment.
Algaecide typically comes in liquid or concentrated forms and can be added directly to the pool water. The application process is simple, but it is crucial to follow the manufacturer’s instructions precisely to avoid overuse, which can lead to staining of pool surfaces or damage to the filtration system. Overusing algaecide can result in an excess of chemicals that can upset the pool’s balance, causing cloudy water or irritation to swimmers’ skin and eyes.
Safety is important when handling algaecide, as with any pool chemical. Always wear protective gloves and goggles to avoid contact with the skin and eyes and store the product out of reach of children. Properly diluting and evenly distributing the algaecide around the pool ensures its effectiveness and prevents potential damage to pool surfaces or equipment.
