PoolFix pH Reducer (Sodium Bisulfate Dry Acid) – Lowers Pool & Spa pH and Alkalinity

Managing proper pH balance is critical to maintaining clear, comfortable, and safe pool water. PoolFix pH Reducer is specially formulated with high-purity sodium bisulfate to lower high pH and alkalinity levels, ensuring your pool water stays balanced and easy to maintain.

When water pH rises too high, it can cause scale deposits, cloudy water, and reduced effectiveness of sanitizers like chlorine. This dry acid formula works quickly to bring levels back into the recommended range, helping protect plaster, tile, and metal surfaces from long-term damage. By reducing alkalinity, it also improves water clarity and enhances swimmer comfort, making each swim more enjoyable.

Pooluxe pH Down is designed for versatility, making it ideal for all pool systems, including chlorine-based, saltwater pools, spas, and hot tubs. Its granular form dissolves easily for fast results, without leaving behind residue or affecting water balance beyond the intended pH adjustment. This makes routine maintenance straightforward and efficient for pool owners of any experience level.

Available in 5lb, 10lb, 30lb, and 45lb resealable buckets, this product is packaged for convenience and ease of use. The durable container allows for secure storage and simple measuring, so you can apply exactly the right amount every time. Whether you are managing a backyard pool, spa, or larger inground system, Pooluxe pH Down provides a reliable, professional-grade solution to maintaining clear, balanced, and inviting water throughout the swimming season.
