The Hidden Dangers of Acidic Pool Water: Why You Should Care
When the temperature rises and pool season begins, we dive into our backyards to enjoy cool, refreshing swims. But what happens when the water isn’t quite right? One common issue pool owners face is acidic pool water. While it might seem like a minor inconvenience, acidic water can cause long-term damage and health issues if left unchecked. Let’s dive into the effects of acidic pool water, why you should pay attention to pH levels, and how to fix the problem.
What Is Acidic Pool Water?
Pool water becomes acidic when its pH level drops below the ideal range of 7.4 to 7.6. The pH scale measures how acidic or alkaline a solution is, with 7 being neutral. Water below 7 is acidic, while anything above 7 is alkaline. In pools, acidic water typically occurs when the pH level falls below 7.0, creating an environment where harmful reactions can occur.
The Health Risks of Swimming in Acidic Water
1. Skin and Eye Irritation
One of the most immediate effects of acidic pool water is the irritation it causes to your skin and eyes. When the pH level drops, it disrupts the natural protective barrier of your skin, leading to dryness, rashes, and itchiness. For your eyes, acidic water can cause redness, stinging, and discomfort. For those with sensitive skin or eyes, the problem can be even more severe, causing lasting irritation long after you've left the pool.
2. Respiratory Issues
Swimming in overly acidic water can also affect your respiratory system. The acidity can irritate your airways, causing coughing, wheezing, and difficulty breathing. While this is more of a concern for individuals with pre-existing respiratory conditions, it’s something anyone should be aware of.
Damaging Effects on Pool Equipment
Acidic water doesn’t just affect the swimmers — it can be incredibly damaging to the pool’s infrastructure.
1. Corrosion of Metal Components
When pool water is too acidic, it can corrode metal parts of your pool, such as ladders, pumps, heaters, and any other equipment that has metal components. Over time, acidic water can weaken these parts, causing leaks and requiring expensive repairs or replacements.
2. Damage to Pool Surfaces
Acidic water can eat away at the surface of your pool, whether it’s plaster, fiberglass, or vinyl. Over time, the finish may deteriorate, leading to rough, uncomfortable surfaces that could even cause scratches or abrasions to swimmers. Pool tiles can also lose their luster, and grout may become stained or eroded.
3. Effect on Pool Liners
For pools with liners, acidic water can cause premature wear. The chemicals in the water can cause the liner material to degrade, leading to leaks or tears. In some cases, it might even change the color of the liner, making it look worn out much sooner than expected.
How to Fix Acidic Pool Water
Now that we know the dangers, let’s talk about solutions. If you find that your pool water is too acidic, there are several ways to raise its pH level and restore balance.
1. Add Alkaline Substances
To raise the pH, you can add substances like sodium bicarbonate (baking soda) or soda ash to the pool water. These help neutralise the acidity. You should always follow the manufacturer’s instructions for the proper dosage to avoid overshooting the pH levels.
2. Use pH Increasers
Many pool supply stores sell pH increasers specifically designed to bring the pH levels back into balance. These are typically made of sodium carbonate or other alkaline chemicals that help counteract acidity.
3. Regular Monitoring and Testing
The key to maintaining a balanced pool is regular testing. Test your pool water at least once a week using a pool test kit to ensure the pH levels stay within the safe range. Pool testing strips or digital testers can quickly give you a readout of the pH, so you can take action before problems arise.
4. Seek Professional Help
If you're unsure about how to adjust the pH level or you're dealing with persistent issues, it’s always a good idea to consult a professional. Pool experts can help diagnose the problem and recommend the best course of action.
Preventing Future Problems
Prevention is always better than cure. By regularly maintaining your pool’s water chemistry, you can keep it balanced and prevent it from becoming too acidic. Make sure to keep an eye on your pool’s alkalinity, as it plays a crucial role in stabilising the pH levels. Proper filtration and circulation also help prevent chemical imbalances that can lead to acidity.
Acidic pool water might not be something you notice right away, but it can have a significant impact on both your health and your pool’s longevity. By maintaining the correct pH levels, you’ll ensure that your pool stays safe, comfortable, and functional for years to come. Remember, a little attention to water chemistry now can save you from costly repairs and uncomfortable swims later. Keep your pool balanced, and dive in with confidence!
