Test daily whether the spa is in use or not, to keep on top of requirements as warm water will need
regular sanitisation.
CHEMICAL WATER TREATMENTS
Bacteria Control –
Use either Rotospa Stabilised Chlorine granules, or Rotospa Bromine infused
granules directly into your spa or alternatively Bromine tablets via a floating or inline dispenser, to
disinfect your spa water and keep it free from bacteria. Pre-mix sanitiser in a plastic container, then
turn the pump on and deposit near the suction point.
To ensure the correct reading is maintained, it is advised that you should aim for the higher end of
the recommended range (5 ppm of chlorine, 6 ppm of bromine). This will act as a useful buffer for
fluctuating conditions, such as high bather loads and hot weather.
The rate of chlorine/bromine consumption can and does vary depending on different conditions and
they will be consumed even when there is no bathing (i.e. just sunlight or heat). Because of this, the
only way to be sure that there is sanitiser present in the water is by testing regularly.
Oxidising –
Regular oxidisation, either weekly or fortnightly, is recommended to remove any excess
contamination and/or remove non filterable wastes. Two ideal products are Rotospa Granular Shock,
or Rotospa Non-Chlorine Shock.
pH Control and Water Balance –
The pH scale of 0-14 measures acidic or alkali conditions
respectively. The middle reading of 7 is neutral, so spa water with a pH below 7 is acidic and spa
water with a pH above 7 is alkaline.
For spa users, the ideal pH level is slightly alkaline, between 7.2 – 7.4, ensuring protection of the spa
equipment and bather comfort is maintained. We recommend always aiming for 7.2 on the pH scale,
as this is the point at which chlorine is most effective.
Maintaining ideal TA (total alkalinity) and total hardness levels will ensure fully balanced water. Low
levels tend to lead to aggressive water, with high levels leaving to scale formation.
TEST IDEAL READING
Free Chorine 3-5 ppm*
Bromine 4-6 ppm
pH 7.2 - 7.6
Total Alkalinity 80 – 150 ppm
*ppm = parts per million
To raise your spa water by 1 ppm of chlorine, add 2g per 1000 litres.
To raise your spa water by 1 ppm of bromine, add 3g per 1000 litres.
