Is it safe to swim in a pool with high bromine?
Bromine is chemically similar to chlorine, and like chlorine, it can burn skin and bleach bathing suits if the concentration is too high. Because it’s volatile, the easiest way to lower bromine levels is to let the water outgas.
Why can bromine be used in swimming pools even though it is toxic?
Because it is a bleach-like chemical, higher concentrations of bromine can cause the above-mentioned skin and respiratory reactions. Because bromine is constantly being removed from the water by environmental factors, simply waiting for the chemical to reach safe levels is usually the only control method needed.
What is better chlorine or bromine?
Bromine works better at higher temperatures than chlorine. Above 75°F, bromine remains stable, whereas chlorine is more effective in temperatures as low as 65°F. This makes bromine a better choice for hot tubs and spas, and an unheated pool will be better served by the use of chlorine.
What to add to pool if bromine is high?
We recommend that you allow the sanitizer levels to break down naturally. But if you have to use your hot tub, then you can add sodium thiosulfate to the water. Sodium thiosulfate will break down both chlorine and bromine in your water.
Does Bunnings sell pool chemicals?
