Raise Total Alkalinity and Help Stabilize Hot Tub pH

Southern Leisure Alkalinity+ raises low total alkalinity and helps maintain a more stable pH balance in hot tub water. Proper total alkalinity helps prevent rapid pH fluctuations and makes routine water balancing easier.

This sodium hydrogen carbonate formula can be dissolved in water or added directly to the spa according to the product label. One 1 lb bottle is included.

🔹 Key Benefits

  • Raises low total alkalinity
  • Helps stabilize spa-water pH
  • Reduces rapid pH fluctuations
  • Makes routine water balancing easier
  • Contains sodium hydrogen carbonate
  • Easy-to-measure granular formula
  • Convenient 1 lb bottle

📋 How to Use

  1. Test the spa water to determine the current total alkalinity.
  2. Add approximately 1 1/4 tablespoons per 250 gallons to raise total alkalinity by approximately 10 ppm.
  3. Dissolve the product in water or add it directly to the spa water according to the bottle directions.
  4. Allow the water to circulate thoroughly.
  5. Retest and repeat as necessary until total alkalinity reaches the desired range.

The product label recommends maintaining total alkalinity between 100 and 150 ppm. Adjust the dosage according to the spa’s actual water capacity and current test result.

Do not mix this product with other chemicals. Add each spa chemical separately.

💬 Southern Leisure Says

Correct total alkalinity before making your final pH adjustment. Alkalinity helps buffer the water, so pH can be difficult to stabilize when total alkalinity is too low.

Make adjustments gradually. Add a measured dose, allow the water to circulate and retest before adding more.

🧼 Care & Maintenance

  • Test total alkalinity and pH regularly.
  • Base each treatment on the spa’s actual water capacity.
  • Use a clean, dry measuring tool.
  • Keep the container tightly closed and dry.
  • Never mix this product with other spa chemicals.
  • Keep out of the reach of children.
  • Always follow the directions and precautions printed on the bottle.
