The Swimming Pool Alum from GS Pool provides professional-grade water clarification for pools suffering from cloudiness or turbidity. Also known as aluminum sulfate, this versatile flocculant binds with suspended particles too small for filters to capture, forming larger clumps that sink to the pool floor for easy vacuuming.
The Swimming Pool Alum represents one of the most versatile and effective tools in professional pool maintenance. When standard filtration cannot remove the microscopic particles that cause water cloudiness, alum provides the solution. The chemical reaction creates aluminum hydroxide floc that acts like a net, capturing particles as small as one micron and aggregating them into clumps large enough to sink.
High CYA levels render chlorine ineffective, forcing pool owners to partially drain and refill. The alum treatment process can achieve significant CYA reduction in about 24 hours, saving thousands of gallons of water. GS Pool provides high-quality alum with the purity and consistency required for these advanced applications. For pool owners and professionals seeking the top rated solution to water quality challenges, Swimming Pool Alum delivers proven performance that justifies its reputation as an indispensable maintenance chemical.

Built with advanced filtration technology, it ensures efficient dirt removal, smooth water circulation, and long-lasting performance for residential and commercial pools.
Swimming Pool Alum, short for aluminum sulfate, is a versatile water treatment compound used primarily as a flocculant to clear cloudy pool water. It works by binding with suspended particles too small for the filter to capture, forming larger clumps that sink to the pool floor for vacuuming. Alum is also useful for phosphate reduction and cyanuric acid reduction.
When alum is added to pool water, it dissociates into positively charged aluminum ions. These ions attract negatively charged suspended particles including dirt, organic matter, and microscopic debris. The particles bind together into larger clumps called floc, which sink to the pool bottom where they can be vacuumed out. This process effectively removes contaminants that cause cloudiness and evade normal filtration.
Alum provides multiple benefits including rapid water clarification, improved filter efficiency, and reduced chlorine demand. It can also help lower phosphate levels that feed algae growth and has been shown to reduce cyanuric acid concentrations when used with proper procedures. These multiple functions make alum the best choice for treating severely cloudy water and improving overall water quality.
For flocculation treatment, first adjust pH to optimal range around 7.0. Broadcast alum evenly over the pool surface with the pump running, then continue circulation for two hours. Turn off the pump and allow floc to settle for at least 12 hours. Vacuum settled debris to waste, not through the filter. For best results, follow this procedure when water is heavily clouded or after algae treatment. GS Pool provides high-quality alum with complete usage instructions.
Alum can also help reduce high cyanuric acid levels without draining the pool. The process involves adjusting pH to 7.0, setting the filter to recirculate, broadcasting alum at approximately 8.3 pounds per 10,000 gallons, running the pump for two hours, then allowing settling for 12 hours. Vacuum the floc to waste and retest cyanuric acid. This method can achieve significant CYA reduction and is the top rated alternative to partial draining.
