Swimming Pool Alum
Swimming Pool Alum (Aluminum Sulfate) is a highly effective, fast-acting flocculant and water clarifier specially formulated to remove suspended particles, cloudiness, and fine debris from residential, commercial, and public swimming pools. Made from premium-grade, purified aluminum sulfate, it rapidly binds with microscopic dirt, algae residues, pollen, and organic matter, causing them to clump together and settle to the pool floor for easy vacuuming, resulting in noticeably clearer and more visually appealing water.
Its powerful coagulation action works by neutralizing the electrical charges of suspended particles, allowing them to combine into larger, heavier clusters that cannot be captured by the pool filter alone. This process dramatically improves water clarity, reduces filter load, enhances filtration efficiency, and restores sparkle to dull or hazy pool water often within hours of application.
Swimming Pool Alum is suitable for all pool types including concrete, vinyl liner, fiberglass, and plaster pools, and is commonly used in homes, hotels, resorts, aquatic centers, and community pools experiencing persistent cloudiness or after heavy rainfall, storms, or high bather loads. It is compatible with most pool filtration systems and water chemistry balances when used as directed.
Designed for user convenience and quick results, this flocculant is easy to apply—typically pre-dissolved in a bucket of water and evenly distributed across the pool surface with the pump turned off. After settling overnight, the consolidated debris can be easily removed via manual vacuuming to waste, bypassing the filter and preventing media clogging.
