Pool Sanitizer Basics
Sanitizing your pool keeps it clean and safe for swimming. Choosing the right sanitizer matters. Two common options are biguanides and chlorine. Understanding their basics helps you decide the best fit.
What Are Biguanides
Biguanides are a type of pool sanitizer without chlorine. They kill bacteria and algae using a chemical called polyhexamethylene biguanide (PHMB). Biguanides do not have a strong smell. They are gentle on the skin and eyes. Pools treated with biguanides often feel softer to touch. This sanitizer works well for people sensitive to chlorine.
What Is Chlorine
Chlorine is the most common pool sanitizer. It destroys germs and algae by breaking their cell walls. Chlorine comes in many forms, like tablets, liquid, or granules. It has a strong smell that some swimmers notice. Chlorine helps keep pool water clear and safe. It also works fast to kill harmful microbes.
How Sanitizers Work
Sanitizers kill harmful bacteria and algae in pool water. They protect swimmers from infections. When added to water, sanitizers release chemicals that attack germs. These chemicals break down the germs’ cell walls and stop their growth. Regular sanitizer use stops the pool water from turning green or cloudy. It keeps the water fresh and safe.
