Maintaining proper pool water chemistry is vital for a safe and enjoyable swimming experience. This 50 lb bag of sodium bicarbonate alkalinity increaser helps to stabilize pH and prevent fluctuations, ensuring a refreshing pool environment. Use this product when total alkalinity drops below 80 ppm. Low alkalinity can cause pH instability, leading to corrosive water and potential damage to pool surfaces and equipment. This granular formula easily dissolves and raises alkalinity levels by approximately 10 ppm per 1.5 pounds added to 10,000 gallons of water. Regular testing and adjustment are essential; retest water after each dosage and allow 4 hours of circulation before swimming. Compatible for use in pools, spas, and hot tubs. Proper alkalinity levels, ideally between 80-120 ppm, protect pool equipment and enhance chlorine effectiveness. This product helps to maintain that balance, protecting your investment and ensuring swimmer comfort. Dosage is adjustable based on pool size and current alkalinity levels; always follow instructions carefully. Contains sodium bicarbonate; a widely used and safe pool chemical. This product does not contain chlorine and is intended to adjust alkalinity, not sanitize the water.
