Adding chlorine to the pool water is a great way to kill viruses and bacteria. The best way to add this ingredient is through a dispenser - known as the chlorine dispenser. With it, you can keep your pool ready for swimming at all times. This tool works by floating around to carry and distribute the chlorine ingredient. It comes with a thermometer and is an affordable piece of equipment which uses sticks and tablets to help clean and sanitize the water in the swimming pool.
