circulation of water can cause the erosion of metals from spa equipment which can present possible

scaling and staining problems in your spa. To remove these simply ﬁll your spa with the Pre-Filter.

In extreme 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.

2. Also, as water evaporates from your spa and new water is added, the amount of dissolved

minerals will increase. The spa water may eventually become “hard” (Calcium Hardness too

high) enough to damage the heater by calcifying its surface. To protect against these problems

add 1 tablespoon (14 grams) per 1000 litres (265 gallons) of Arctic Pure

Best Defense weekly.

Balance the Total Alkalinity (TA)

1. The recommended Total Alkalinity (TA) for your spa water is 125-150 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

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 slightly higher pH range for your spa water; 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.

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.
