At Leisure Industries, we carry a number of pool sanitizer products. If you’re ever unsure what you need, don’t hesitate to contact us or come down to our store to speak with a staff member. Using our information below, you will be able to browse the different pool sanitizer chemicals, along with Features and Benefits of each. All pools and spas must be sanitized with chlorine or bromine to ensure the water is safe to swim in. But with certain systems you can reduce that amount and still be able to maintain a safe, enjoyable pool or spa.
