Sodium Bicarbonate 100%...Antacid
• add 1/2 teaspoon to 1/2 glass (4 fl. oz.) of water every 2 hours, or as directed by 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. Each 1/2 teaspoon contains 616mg sodium. 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: If pH is less than 7.2, add 3-4 lbs. per 10,000 gallons of water. 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: If alkalinity is 20 ppm, add 12 lbs. per 10,000 gallons of water. If alkalinity is 40 ppm, add 9 lbs. per 10,000 gallons of water. If alkalinity is 60 ppm, add 6 lbs. per 10,000 gallons of water. If alkalinity is 80 ppm, add 3 lbs. per 10,000 gallons of water. If alkalinity is 110 ppm or higher, don't add Baking Soda. By controlling alkalinity at the proper range of 80-100 ppm, the pH will usually stabilize in its desired range. However, occasional pH adjustment may be necessary. Therefore, pH also should be measured every week. If pH is high, add sodium bisulfate or acid in moderation to reduce pH. If pH is low, but the alkalinity is in the proper range, don't add baking soda (sodium bicarbonate). Adjust pH by adding a chemical with high pH such as soda ash (sodium carbonate) to raise pH rapidly without significantly increasing alkalinity. Points to Remember: 1. Regularly check disinfectant level, and add disinfecting agent as recommended by the manufacturer. 2.
