Concentrations of 0, 5 mg/L of Sodium Bromide lead to irritations on mucous membranes, eyes and odor nuisance. The UE standard for bromine in swimming pools is 0, 7 mg/L.

The Sodium Bromide level in your hot tub and spa should be between 1500 – 1900 ppm. To ensure that you do not overdose and exceed the correct dosage, it is suggested to put in less rather than more Bromide to your water.

You must take care that over time the water level in your hot tub or spa will decrease caused by evaporation . It will exceed the concentration of Sodium  in your spa since evaporation doesn’t reduce the amount of Sodium Bromide. However, water removal (exiting bathers, splashing, etc) will decrease the amount of some Bromide.
