Pool Mate pH Up & Alkalinity Increaser for Pools, 25-Pound Bundles

This 25-pound pool chemical bundle contains two complementary products to help maintain proper water chemistry in your swimming pool. The Pool Mate pH Up raises pH levels, while the Pool Mate Alkalinity Increaser boosts total alkalinity. Using them together provides complete pH control. The Pool Mate pH Up contains sodium carbonate to rapidly increase pH if it drops below the recommended 7.2-7.6 range. Proper pH prevents pool surface erosion and etching. The easy-to-use 25-pound bucket should be pre-dissolved then poured around the pool perimeter while the circulation system runs. Retest and reapply if necessary to reach the desired pH. The Pool Mate Alkalinity Increaser uses sodium bicarbonate to raise total alkalinity, which should be maintained between 70-140 ppm depending on your pool type. Proper alkalinity prevents pH bounce, boosts the effectiveness of pool disinfectants, and helps avoid corrosion and plaster damage. The included dosage chart makes it simple to add the recommended amount if your alkalinity dips too low. Using these two products together provides complete pH protection by both raising pH and stabilizing it at the proper levels. The bundled 25-pound buckets ensure you have the right chemicals on hand for clean, balanced pool water all season long.

• Raises pH to optimal 7.4-7.6 range to prevent erosion of pool surfaces with 25 lbs of sodium carbonate (component 1)
• Maintains total alkalinity between 70-140 ppm to stabilize pH and prevent corrosion with 25 lbs of sodium bicarbonate (component 2)
• Component 1 dissolves rapidly to quickly adjust low pH levels below 7.2
• Component 2 boosts effectiveness of pool disinfectants
• Both components easily pre-dissolve before pouring around pool perimeter
