Hot Tub Things pH and Alkalinity Down 1.25 Pounds - Keep Your Spa Water Properly Balanced

pH Down is designed to decrease both alkalinity and pH of your pool, spa, or hot tub. Ideally, the total alkalinity should be between 80 and 150 ppm, and pH between 7.2 and 7.8. Use: pH Down should be used as necessary when pH levels are above 7.8. 1. Make sure all equipment is OFF. 2. Add 1/4 oz. (1-1/2 tsp.) pH Down for every 500 gallons of spa water. 3. Turn ON circulation system for 30 minutes. 4. Retest water. If pH is still above 7.8, repeat steps 1-3. NOTE: For best results, dissolve granular products first by adding to a small, container of water. Then, apply the solution to the spa water.
