Chemical care
In order to take care of your spa investment and your health, you must maintain correct chemical
levels of sanitizer, oxidizer and pH balance.
Failure to do so may cause damage to equipment not covered by warranty, or risk your health.
Correct recommended ranges are listed below:
Sanitiser – lithium hypochlorite
1.0-3.0 ppm
pH
7.2-7.8
Total Alkalinity
80-100
Calcium Hardness
200-400
We recommend the use of test strips or digital test strip reader to monitor your chemical levels.
Testing must be carried out twice per week to ensure proper levels.
We do not recommend you rely on pool shop testing if carried out less frequently than twice per
week.
All chemical level adjustments made after an initial test, require re-testing to ensure the level has
been corrected.
Please note that we do not recommend the use of the following products / systems as damage to
equipment is far more frequent due to the extremely high maintenance levels required and
neglected.
Bromine tablets – these have a very low pH so are essentially an acid that sanitises requiring daily
monitoring and adjustments.
Salt chlorination – salt remains in solution and is very abrasive to heaters. Chlorine gas is ineffective
in water over 26 degrees and if there is no ORP control, levels easily exceed maximum levels advised.
We recommend the use of Lithium Hypochlorite as a sanitizer – its an all-round proven performer at
moderate pricing, easy to use and low effect on pH.
Our recommended chemical range:
Sanitiser:
Lithium Hypochlorite – granular spa chlorine (do NOT use pool chlorine)
Oxidiser:
Potassium Mono-persulphate
pH decreaser:
Dry acid
pH increaser:
Soda Ash
pH buffer:
Bi-Carbonate Soda
If you are using tank water you will also need to use a Hardness Increaser. Bore water use may
require a softener.
If you are allergic to Chlorine an alternate chlorine free spa chemical system may need to be
considered.
We recommend against the addition of any other spa chemical product than those listed above.
