Ingredients: Active: Sodium Bicarbonate.

Usage Directions / Dosage: Add 1/2 teaspoon to 1/2 glass (4 fl oz) water every 2 hours, or as directed by a physician. Dissolve completely in water. Accurately measure 1/2 teaspoon. Do not take more than the following amounts in 24 hours: Seven 1/2 teaspoons. Three 1/2 teaspoons if you are over 60 years. Do not use the maximum dosage for more than 2 weeks. For sparkling clear pool water: How to use: For those who monitor pH only: Every week during the swimming pool season, measure the pH and add Arm & Hammer baking soda as indicated below. If pH is less than 7.2 add per 10,000 gallons of water 3 - 4 lbs. If pH is between 7.2 - 7.5 add 2 lbs per 10,000 gallons of water. If pH is above 7.5 don't add baking soda. To prevent clouding, especially in hard water areas (250 ppm or more) or when using a calcium chlorinating agent, keep the pH below 7.8 by adding sodium bisulfate or acid if necessary. For those who monitor both pH and alkalinity: Pool professionals advise that baking soda (sodium bicarbonate) be used to provide alkalinity (proper range 80 - 100 ppm), and that alkalinity and pH be controlled independently. Every week during the season, measure the alkalinity and add Arm & Hammer baking soda as indicated below. If alkalinity is 20 ppm add per 10,000 gallons of water 12 lbs. If alkalinity is 40 ppm add per 10,000 gallons of water 9 lbs. If alkalinity is 60 ppm add per 10,000 gallons of water 6 lbs. If alkalinity is 80 ppm don't add baking soda. For Laundry Freshening: Improves your liquid laundry performance. Add 1 cup with liquid laundry detergent for cleaner fresher laundry.
