What are the differences between chlorine, bromine, biguanide (Baquacil), and salt systems?
Chlorine is the most common and least expensive sanitizer for your pool, however it requires more frequent applications since chlorine burns off quickly in sunlight or heat. Chlorine becomes an ineffective santizer when it comes in contact with ammonia to form chloramines. Chlorine is less expensive to purchase. Normal levels are 1-3 ppm. NEVER MIX BRANDS OF CHLORINE OR FORMS OF CHLORINE. Bromine has 2 advantages over chlorine: When it combines with ammonia and forms bromamines, it still sanitizes. Also bromamines do not cause the irritation that chloramines do. Bromine cannot be stabilized to slowdown deterioration from sunlight. Normal levels are 1-3 ppm, like chlorine. Biguanides require less frequent water care than Chlorine and Bromine but water care products cost a little more. When shocking a biguanide pool, use a liquid with hydrogen peroxide as the active ingredient. Normal levels are 30-50 ppm. BE AWARE OF CHEMICAL INCOMPATIBILITY. Salt systems work with salt and a stabilizer
