The following sections highlight five products most relevant to maintaining proper pool pH. Each entry provides a quick overview, practical uses, and key features to help you compare options and choose the right product for your pool.
Clorox Pool&Spa pH Up for Pools

Clorox Pool&Spa Swimming Pool pH Up is formulated to elevate low pH levels, restoring water chemistry to ideal ranges. By increasing pH, it helps create a balanced swimming environment and supports swimmer comfort by reducing eye and skin irritation associated with acidic water. Keeping pH in range also protects pool equipment from corrosion, enabling more time enjoying rather than maintaining your system.
Key uses include correcting low pH after heavy rainfall, high sanitizer demand, or the addition of acidic cleaners. Apply as directed, typically in small, measured doses to avoid overshooting pH targets. Regular testing remains essential to maintain steady pH levels.
Clorox Pool&Spa pH Down for Pools

Clorox Pool&Spa Swimming Pool pH Down is designed to lower high pH levels to neutral ranges, supporting a balanced and healthy swimming environment. It also helps prevent scale buildup and offers an easy-pour design with splash-free application, making pH adjustment safer and more convenient. By maintaining proper pH, the product helps protect pool surfaces and equipment from corrosion.
Use when pH readings exceed the target range or after disruptions such as rainfall or high sanitizer usage. Always re-test after a dosing interval to confirm measurements and adjust as needed to avoid overshooting pH.
Pool Mate pH Up 10-Pounds

Pool Mate 10-Pounds Premium pH Up uses sodium carbonate to raise pool pH rapidly. This product helps stabilize water chemistry and reduces the risk of acidic conditions that can erode pool surfaces. It is particularly effective for pools that experience frequent pH dips due to heavy bather load, rain, or sanitizer additions. Proper dissolution and dosing are important to prevent localized high concentrations.
When adding this product, disperse slowly around the pool while the pump is running. Re-test after circulation to verify the target pH is reached, and adjust in small increments as necessary for best results.
Arm & Hammer Clear Balance Alkalinity Tablets

Arm & Hammer Clear Balance Swimming Pool Alkalinity pH Maintenance Tablets provide a convenient way to maintain alkalinity, which helps stabilize pH levels. The tablets leverage trusted ARM & HAMMER Baking Soda to support chlorine effectiveness and protect pool surfaces from corrosion. The tablet form minimizes mess and dosing complexity; simply add one tablet for each chlorine tablet to optimize overall pool chemistry.
Regular use helps reduce pH swings, contributing to clearer water and more consistent swimmer comfort. For best results, pair with routine testing and adjust dosing as needed based on test results and pool usage patterns.
HTH 67058 pH Up for Pools

HTH 67058 Swimming Pool Care pH Up raises pH levels to improve clarity, chlorine efficiency, and overall pool health. Balanced pH helps prevent corrosion of pool surfaces and enhances swimmer comfort by reducing eye and skin irritation. This product is suitable for various pool types and works best when used in combination with regular water testing and proper filtration cycles.
Apply according to label directions, re-test after stabilization time, and adjust if needed. Maintaining a consistent pH range supports more effective sanitization and extends equipment life.
Buying Guide
- Know your target pH range: Most pools aim for a pH between 7.2 and 7.6. Choose a product that helps you reach and maintain that range.
- Choose based on impact type: Use pH Up products to raise pH, pH Down products to lower pH, and alkalinity maintenance products to stabilize both pH and total alkalinity.
- Consider ease of use: Tablet formats offer convenience for maintenance routines, while granular powders may provide faster on-site adjustments. Pick a format that aligns with your routine.
- Test regularly: Consistent testing with test strips or a test kit ensures accurate dosing and stable water chemistry, preventing irritation and equipment damage.
- Safety and handling: Follow label directions, wear protective gear as needed, and store products in a cool, dry place away from children and pets.
- Pool type considerations: Some products are designed for specific pool types or water alkalinity ranges. Ensure compatibility with your pool’s surface and filtration system.
- Compatibility with other chemicals: When adjusting pH, ensure you do not rapidly mix multiple chemicals. Add products separately and allow time for circulation between applications.
