Remove Excess Minerals
Most tap water has minerals such as Calcium, Copper, Iron, Manganese and Sodium in it, and the
circulation of water can cause the erosion of metals from spa equipment which can present possible scaling
and staining problems in your spa. Cases of source water with high minerals (such as some well water):
- 1. We recommend you add 3 1/2 tablespoons (48 grams) of Arctic Pure ® Best Defense
per 1000 litres (265 gallons) of water while filling your spa.
Balance the Total Alkalinity (TA)
1. The recommended Total Alkalinity (TA) for your spa water is 80-120 ppm.
2. Total Alkalinity is a measure of the total levels of carbonates, bicarbonates, hydroxides, and
other alkaline substances in the water. TA is referred to as the water's "pH buffer". In other
words, it's a measure of the ability of the water to resist changes in pH level.
3. If the TA is too low, the pH level will fluctuate widely from high to low. Fluctuations in pH
can cause corrosion or scaling of the spa components. Low TA can be corrected by adding
Arctic Pure TM Perfect Balance.
4. If the Total Alkalinity is too high, the pH level will tend to be high and may be difficult to bring down. The
pH can be lowered by using Arctic Pure ® Adjust Down.
5. Once the TA is balanced, it normally remains stable, although some sanitizers, and the
addition of more water with a high or low alkalinity will raise or lower the TA reading of the
water.
6. When the Total Alkalinity is within the recommended range, proceed to the next step.
Balancing the pH
1. We recommended a pH range for your spa water of; 7.2-7.6
.
2. The pH level is the measure of acidity and alkalinity. Values above 7 are alkaline; those
below 7 are acidic. Maintaining the proper pH level is extremely important for:
• Optimizing the effectiveness of the sanitizer.
• Maintaining water that is comfortable for the user.
• Preventing equipment deterioration.
• Preventing cloudy or odorous water.
3. If the spa water's pH level is too low, the following may result:
• The sanitizer will dissipate rapidly.
• The water may become irritating to spa users.
• The spa's equipment may corrode.
If the pH is too low, it can be increased by adding Arctic Pure ® Adjust Up to the spa water.
4. If the pH level is too high, the following may result:
• The sanitizer is less effective.
• Scale will form on the spa shell surface and the equipment.
• The water may become cloudy.
If the pH is too high, it can be decreased by adding Arctic Pure ® Adjust Down to the spa water.
5. It is important to check the pH on a regular basis. The pH will be affected by the bather
load, the addition of new water, the addition of various chemicals, and the type of sanitizer
used.
6. When the pH is within the recommended range, proceed to the final step.
