Product details
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.
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.
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.
