👉 The pool fluid, also known as pool chemical or pool water treatment chemicals, is a mixture of various substances added to swimming pools to maintain water quality, balance pH levels, prevent algae growth, and ensure the longevity of pool equipment. Common components include chlorine or chloramines for disinfection, pH adjusters to keep the water's acidity within a safe range, algaecides to inhibit algae formation, and coagulants or flocculants to remove dirt and organic matter. Proper pool fluid management is crucial for creating a safe, clean, and visually appealing swimming environment.
