SpaGuard Total Alkalinity Increaser

The product number 42630BIO corresponds to a 2-pound container of SpaGuard Total Alkalinity Increaser. This granular product is used to raise the total alkalinity (TA) level in hot tub and spa water, an essential part of maintaining balanced water chemistry. 

Key Features and Description:

• Purpose: To increase low total alkalinity levels in spa water. The ideal range for total alkalinity in a spa is generally between 125-150 ppm (parts per million).

• Active Ingredient: The product is 100% Sodium Hydrogen Carbonate (also known as sodium bicarbonate or baking soda).

Benefits:

• Prevents pH Bounce: Proper alkalinity acts as a buffer, stabilizing the pH level and preventing rapid fluctuations ("pH bounce") that can occur when adding other chemicals or due to bather use.

• Protects Equipment: Low alkalinity can cause the water to become corrosive, leading to etching, staining, and damage to metal equipment (like heaters) and spa surfaces.

• Maximizes Sanitizer Efficiency: When water is balanced correctly, sanitizers (chlorine/bromine) work at peak efficiency to keep the water clean and safe.

• Enhances Comfort: Maintaining the correct pH and alkalinity levels prevents skin and eye irritation for bathers.
