Bromine

Bromine is a powerful sanitizer like chlorine, but it's much less harsh on the skin and eyes. Works in a wide pH range of 6.8 to 8.4. Unlike chlorine, used bromine or bromamines still sanitize effectively. Its greater stability in hot water makes it perfect for spas also. Use 17 tablets per 10,000 gallons every 5-7 days. Dissolves 1/10 as fast as chlorine. Use of a dispenser is required.
