1kg Bromine Granules

Bromine Granules are a highly effective sanitiser formulated to kill and prevent bacteria in your hot tub water.


Bromine Granules are ideal for daily dosing of your spa, to produce active bromine which kills bacteria and other potentially harmful organisms.

  • They are rapid dissolving and have minimal impact on pH
  • Use spa test strips and ph balance products to maintain pH level within the ideal range of 7.2 – 7.6.
  • Maintain bromine residuals for spas within the range 3 -5 mg/l (ppm)
  • These bromine granules may be applied directly to spas where temperatures exceed 20 degrees C.
  • If below this temperature or if in doubt pre-dissolve the chlorine granules in a clean plastic container at a maximum rate of 10g of product per 0.2 gallons (1lt) of water.
  • Stir well to ensure the chlorine is fully dissolved.
  • Carefully add the resulting solution to the spa whilst the pump(s) are turned on, preferably near the water inlets and jets to aid distribution.
  • Repeat dose application if necessary to achieve levels in point 2 above.
  • Use spa test strips to check the chlorine level is within the range 3 – 5mg/l (ppm) before bathing recommences.

It is recommended that you periodically shock dose your spa with Aquasparkle spa fusion.
