Bromine is a powerful and effective sanitizer like chlorine, but it is much less irritating to your skin and eyes, produces no chlorine odor and makes your pool or spa water silky smooth! Unlike chlorine, bromine's unique feature is that the "dead" or "used" bromine cells that normally get filtered or splashed out of the water can be re-used as long as new bromine is being introduced into the water. Bromine also dissolves at a much slower rate than chlorine and requires a special automatic feeder. Bromine is a "pre-stabilized" chemical, so it does not require the use of stabilizers or pool water conditioner, which saves you money and enhances your pool enjoyment.
