Contrary to what manufacturers claim about pool tablets, our testing revealed that not all are created equal. After hands-on experience with several options, I can tell you the key is how well they balance sanitation, protect surfaces, and dissolve steadily. The best pool cleaning tablet should keep your water clear, sanitize effectively, and last long enough to avoid constant refills. That’s why I recommend the ARM & HAMMER Clear Balance Swimming Pool Alkalinity pH tablets. They combine pure baking soda with a powerful formula that boosts chlorine performance while protecting your pool surfaces from corrosion. Plus, they’re simple to use—just drop one tablet per chlorine tablet—and they produce crystal-clear water that feels gentle on your skin.
After thorough comparison, this product stood out by effectively maintaining balanced pH levels and enhancing chlorine efficiency, all in a convenient, mess-free tablet form. While other options like the Clorox XTRABLUE and Profeliz chlorine tablets are great for algae and bacteria control, they don’t address pH and alkalinity as naturally or simply. Trust me, with ARM & HAMMER’s proven formula, you get reliable long-term maintenance, making your pool experience much better.

What Ingredients Make Up Quality Pool Cleaning Tablets?
The best pool cleaning tablets typically consist of several key ingredients that ensure effective water treatment and sanitation.
- Chlorine: A primary ingredient in most pool cleaning tablets, chlorine effectively kills bacteria and algae, keeping the water clean and safe for swimming. It works by releasing hypochlorous acid when dissolved in water, which is the active form that disinfects the pool.
- Stabilizers (Cyanuric Acid): These compounds help protect chlorine from being broken down by sunlight, extending its effectiveness in outdoor pools. By maintaining an optimal level of stabilizer, pool owners can ensure that chlorine levels remain consistent, reducing the frequency of chemical additions.
- Algaecides: Some tablets include algaecides to prevent and control algae growth, which can cause water discoloration and slippery surfaces. These substances work alongside chlorine to enhance the overall sanitation process, ensuring a clearer and healthier pool environment.
- pH Balancers: Ingredients that help maintain the pH level of the pool water are often included, as balanced pH is crucial for effective chlorine performance and to prevent skin and eye irritation for swimmers. Tablets may contain acids or bases that adjust the pH levels to the desired range.
- Clarifiers: These agents help to clear cloudy water by coagulating tiny particles, making it easier for the pool filter to remove them. Clarifiers improve water clarity, allowing for a more pleasant swimming experience and ensuring that the pool looks inviting.
How Do Pool Cleaning Tablets Work to Keep Water Clean?
Pool cleaning tablets are essential for maintaining clean and clear water in swimming pools by providing sanitation and balancing water chemistry.

What Common Mistakes Should You Avoid When Using Pool Cleaning Tablets?
When using pool cleaning tablets, it’s essential to avoid several common mistakes to ensure effective cleaning and maintain pool health.
- Using the Wrong Type of Tablet: Different pool cleaning tablets are formulated for specific purposes, such as sanitization or algaecide. Using the wrong type can lead to ineffective cleaning and may cause chemical imbalances in the pool water.
- Not Following Dosage Instructions: Each pool cleaning tablet has specific dosage guidelines based on the pool size and type of treatment required. Overdosing can lead to chemical buildup and potentially harm pool equipment, while underdosing may not effectively sanitize the water.
- Inadequate Dissolution: Pool cleaning tablets must be allowed to dissolve properly for maximum effectiveness. If they are placed in areas with low circulation or not in the skimmer basket, they may not dissolve evenly, leading to uneven distribution of cleaning agents in the water.
- Ignoring Water Chemistry: Regularly test the pool water chemistry before and after using cleaning tablets. Failing to do so can result in imbalanced pH or chlorine levels that can affect swimmer comfort and pool equipment longevity.
- Not Storing Tablets Properly: Pool cleaning tablets should be stored in a cool, dry place away from direct sunlight and moisture. Improper storage can lead to degradation of the tablets, making them less effective when you need to use them.
- Using Tablets in a Dirty Pool: If the pool is heavily contaminated with debris or algae, simply adding cleaning tablets may not be sufficient. It’s essential to vacuum and clean the pool prior to using tablets to ensure they work effectively.
- Neglecting Regular Maintenance: Cleaning tablets are not a substitute for regular maintenance routines, such as brushing, vacuuming, and skimming. Relying solely on tablets can lead to build-up of algae and dirt, requiring more intensive cleaning efforts later.
