Water Quality and Maintenance
Testing and Adjusting Water Chemistry
- Before using your spa, it is important to test the water so that it maintains the correct chemical
balance. This will ensure water quality, clarity and help keep your spa equipment in good condition.
- Y
ou will need to test and adjust the chemical balance of your spa water. Although this is not difficult,
it needs to be done regularly.
There are 2 types of testing methods:
- The reagent test kit is a method which provides a high level of accuracy. It is available in either
liquid or tablet form.
- Test strips are a convenient testing method com-monly used by spa owners.
- You can purchase the test kits and chemicals locally or from our website @

Balancing the Total Alkalinity
- Total alkalinity (TA) is the measure of the total levels of carbonates, bicarbonates, hydroxides, and
other alkaline substances in the water. TA can be considered a pH buffer. It is the measure of the
ability of the water to resist changes in pH level.
- The recommended total alkalinity is 80 - 120
ppm.
- If the TA is too low, the pH level will fluctuate widely from high to low. Low TA can be corrected by
adding alkalinity increaser.
- If the TA is too high, the pH level will tend to be too high and may be difficult to bring down. High
TA can be corrected by adding pH decreaser.
- When the TA is balanced, it normally remains stable, although adding water with high or low
alkalinity will
raise or lower the TA level.
Balancing the Calcium Hardness
- Calcium hardness (CH) is a measure of the total amount of dissolved calcium in the water. Calcium
helps control the corrosive nature of the spa’s water and is why soft water is not recommended. The
low calcium content of soft water is very corrosive to the equipment and can cause staining of the spa
shell.
- The recommended calcium hardness is
150 - 200 ppm.
- If the CH is too low, add liquid hardness increaser.
- If the CH is too high, dilute the spa water with soft water or, if this is not available, add stain and
scale defense.
- When the CH is balanced, it normally remains sta-ble, although adding soft water or very hard water will raise
or lower the CH level.
