Are you tired of murky, cloudy pool water ruining your summer fun? Maintaining a clean and inviting swimming pool is crucial for the health and enjoyment of you and your loved ones.
Fortunately, there's a simple solution that has been trusted for centuries: Aluminium Sulphate, also known as Alum. This powerful water treatment chemical is the key to achieving sparkling, transparent pool water.
In this post, you'll learn how alum improves water clarity, controls algae, and balances pool pH.
Aluminium Sulphate, or Alum, is a chemical compound with the formula Al2(SO4)3. It's a white, granular powder that dissolves easily in water.
Alum is made up of two main components: Aluminium (Al) and Sulphate (SO4). When combined, they form a powerful molecule with unique properties.
These properties make Alum an ideal choice for water treatment applications.
In swimming pools, Alum acts as both a flocculant and coagulant. Here's how it works:
1. Attraction: The positively charged Alum molecules attract negatively charged particles in the water, such as dirt, algae, and other impurities.
2. Clumping: As the Alum binds to these particles, it forms larger clumps called "flocs."
3. Settling: The flocs become heavy and sink to the bottom of the pool, making it easier to remove them through vacuuming or filtration.
Aluminum sulfate, known as alum, has a long history. Ancient Egyptians used alum for water clarification. Hieroglyphics describe "aluminum earth" in their purification processes. Similarly, ancient Greeks and Chinese also utilized alum for clearing water. Documents from the first century detail alum mining and its application in making water clear.
By the 16th century, alum's use expanded across England. Municipalities used it to treat public water supplies. Its effectiveness in removing suspended particles and improving water quality made it indispensable. This marked a significant development in water treatment history.
Today, aluminum sulfate is still a key player in water treatment. It is widely used in water treatment facilities. Its role as a flocculant and coagulant helps remove impurities from water. This ensures clean and safe drinking water for communities.
In addition to public water systems, alum is crucial in pool maintenance. Pool owners use aluminum sulfate to keep pool water clear and balanced. It helps control algae and maintain optimal pH levels. By removing contaminants, it ensures crystal-clear water for a pleasant swimming experience.
Aluminum sulfate, or alum, is essential for treating extremely cloudy or swampy pools. Pools left neglected can become murky and uninviting. Draining and refilling the pool isn't always practical. Instead, alum can clear the water without the need to drain. By acting as a flocculant, it attracts and binds suspended particles. These clumps then settle at the pool's bottom, ready for vacuuming. This method preserves water and avoids the hassle of refilling.
Pollen season can turn a pristine pool into a yellow mess. Heavy rain can also introduce contaminants, affecting water clarity. Aluminum sulfate is effective in these situations. When pollen coats the pool surface, alum helps by coagulating these tiny particles. Similarly, after heavy rain, it can clear debris and impurities from the water. Simply broadcast the proper dosage of alum across the pool. Run the filtration system, and watch as the pool water returns to its crystal-clear state.
Routine pool maintenance is key to preventing impurities from building up. Regular use of aluminum sulfate helps keep the pool in top condition. It maintains water clarity and balances pool chemistry. For optimal results, follow a maintenance schedule. Regularly test water pH levels and ensure proper chemical balance. Use alum as a preventive measure, not just a reactive one. This practice will keep the pool water clean, clear, and inviting.

Before adding alum, it's crucial to get your pool in tip-top shape:
1. Skim, Vacuum, and Brush: Remove large debris, vacuum the bottom, and give the walls a good brushing. This helps the alum work more effectively.
2. Balance Pool Chemistry: Test and adjust your pool's pH (7.2-7.6), alkalinity (80-120 ppm), calcium hardness (200-400 ppm), chlorine (1-3 ppm), and cyanuric acid (30-50 ppm). Balanced water is key for optimal results.
Now that your pool is prepped, it's time to apply the alum:
1. Broadcast the Alum: Spread the recommended amount of alum evenly over the pool surface. Aim for 4 lbs per 10,000 gallons of water.
2. Run the Pump: Turn on your pump and let it run for 2 hours. This helps distribute the alum throughout the pool.
3. Brush the Pool: Give your pool another thorough brushing to help the alum bind to suspended particles.
4. Let it Settle: Turn off the pump and allow the alum to work its magic for 12-24 hours. You'll see the flocs settle to the bottom.
5. Vacuum to Waste: Set your multiport valve to "Waste" and vacuum up the settled flocs. This removes them from your pool entirely.
The amount of alum you'll need depends on your pool size and water condition. Here's a general guide:
| Pool Condition | Dosage per 10,000 gallons |
|----------------|---------------------------|
| Clean Water | 2-4 lbs |
| Cloudy Water | 4-6 lbs |
| Green Water | 6-8 lbs |
Remember, it's always better to start with a lower dose and add more if needed. Too much alum can cause pH imbalances and other issues.
Using aluminum sulfate in your pool is simple, but there are a few key things to keep in mind. Let's dive into some practical tips and precautions.
When it's time to vacuum up the settled alum flocs, take it slow:
Slow and Steady: Move the vacuum head slowly across the bottom of the pool. If you go too fast, you risk stirring up the flocs and undoing your hard work.
Add Fresh Water: As you vacuum to waste, you'll be removing water from your pool. Keep a garden hose running to replace what's lost.
If you're dealing with an algae bloom, alum alone might not be enough:
Shock Treatment: After adding the alum, consider using 2-4 lbs of shock per 10,000 gallons of water. This extra boost can help knock out stubborn algae.
Alum works best when your pool water is in the Goldilocks zone:
Optimal Range: Aim for water temperatures between 70-80°F (21-27°C). This is when alum is most effective at binding to particles.
Cold Water: Alum can still work in colder water, but it might take a bit longer to do its job.
As with any pool chemical, safety should be your top priority:
Accurate Dosing: Measure carefully and follow the recommended dosages. Too much alum can throw off your pool's pH balance.
Protective Gear: Wear gloves and eye protection when handling alum. Avoid breathing in the dust.
Storage: Keep alum in a cool, dry place away from other chemicals and out of reach of children and pets.
In this article, we've explored the remarkable benefits of using Aluminum Sulfate (Alum) in swimming pools. From crystal-clear water to effective algae control and balanced pH levels, Alum is a powerful tool in pool maintenance.
However, to reap the full benefits of this chemical, proper application and monitoring are crucial. By following the recommended dosages, preparation steps, and safety precautions, you can harness the power of Alum effectively.
Maintaining a clean pool with alum is simple. It ensures a healthy swimming environment. Regular use of alum keeps your pool water clear, safe, and inviting.
