Know before you buy
Total alkalinity acts as a buffer for your spa water, preventing rapid fluctuations in pH levels, also known as 'pH bounce.' Maintaining the correct level protects your spa equipment and surfaces from corrosion while ensuring your sanitizer works as efficiently as possible.
The recommended dosage is 1 tablespoon per 100 gallons of water, which will raise your total alkalinity by approximately 25 ppm. Always test your water first to determine your current levels and calculate the exact amount needed to reach the target of 150 ppm.
Simply broadcast the granular formula directly into the spa water while the pump is running. Keep the pump running on high speed for at least 30 minutes after application to ensure the product is fully dissolved and circulated.
Yes, SpaGuard Alkalinity Increaser is compatible with chlorine, bromine, ozone, and biguanide sanitizers. However, please note that it is not compatible with saltwater spa systems.
While the primary purpose of this product is to raise alkalinity, it is not pH neutral. Because alkalinity and pH are closely linked, you should always test your water chemistry after the product has fully circulated to see if a pH adjustment is necessary.
