WATER MAINTENANCE – RECOMMENDED RANGES
WATER CHEMISTRY GUIDE
Before treating your water, refer to the Model Specifications section of this manual for the
correct gallons of your swim spa, to ensure you are adding the correct amount of chemicals. The
concentration of active ingredients in swim spa chemicals varies by manufacturer, so always consult
chemical manufacturer's instructions. When adding swim spa chemicals, always spread them across
the surface of the water while the pumps are running. See chart below for recommended ranges.
PARAMETER
Water Clarity
Color of Water
Turbidity in FNU/NTU
Nitrate concentration above that of fill water (in mg/l) max. difference of 20 compared to
Total organic carbon (TOC) (in mg/l)
Redox potential against Ag/AgCI 3,5 M KCl in mV
pH value
e, f
Free active chlorine (without cyanuric acid) (in mg/l)
Free chlorine used in combination with cyanuric acid
(in mg/l)
Cyanuric acid (in mg/l)
Combined chlorine (in mg/l)
Bromine
(in mg/l)
When using alternative/additional disinfectants other appropriate parameters may be considered.
a
Consult national regulations and guidelines for any deviations.
b
Natural water sources may introduce water colouration.
c
Intentional water colouration is excluded.
d
When using organic compounds this value may be higher.
e
Subject to the flocculant(s) used (if any).
f
When pH is greater than 7,5 the free active chlorine is less than 50 %.
g
Temporary exceeding due to manual dosage and low water volume to user ratio is acceptable, provided the
health of the user is not compromised.
h
If national regulations allow > 100 mg/l then a suitable treatment should be applied (e.g. dilution).
i
If national regulations allow > 0,5 then a suitable treatment should be applied (e.g. dilution)
NOTE:
The Indicative physical and chemical parameters when using chlorine disinfectant outlined in this
manual are specified to comply per EU regulation (BS EN 17125:2018). Regulatory agencies in countries
outside of the EU may require different values than what is outlined here. If the swim spa is installed in
a country outside of the EU, check with your local regulatory body for recommended chemical levels in
your area. Improper use of chemicals may result in unsanitary and unsafe water conditions as well as
unwarranted discoloration, degradation, damage and other imperfections of the swim spa surface and
components.
