Should You Use Soft Water in Your Pool?
Quick Summary: Using soft water in your pool reduces scaling and feels gentler on skin but can cause corrosion and water balance issues. It lacks essential minerals, making pH and alkalinity harder to maintain. To prevent damage, regularly test water chemistry, add calcium as needed, and consider mixing softened and unsoftened water. If you have a saltwater pool, monitor sodium levels. Proper management ensures a safe, enjoyable swim.
Using soft water in your swimming pool comes with both advantages and challenges. While it helps prevent scaling and provides a more comfortable swimming experience, it also requires careful water balance management to avoid corrosion and instability. If you choose to use softened water, be proactive in testing and adjusting your pool water chemistry to maintain a healthy and long-lasting swimming environment.

Using Soft Water for Your Pool: Benefits, Risks, and Best Practices
When it comes to maintaining a clean, safe, and enjoyable swimming pool, water quality is paramount. Many pool owners are familiar with using chlorine, shock treatments, and pH balancers, but one question that often arises is whether soft water is a good choice for swimming pools. As a leading water treatment expert, Culligan is here to break down the pros and cons of using soft water in your pool and provide best practices for keeping your pool water balance in check.
What Is Soft Water?
Soft water is water that has been treated to remove excess calcium and magnesium, which are the minerals responsible for water hardness. This is typically done through a water softener, which exchanges these hard minerals for sodium or potassium. The result is softened water that is free from scale from water hardness, gentler on skin and hair, and better for household appliances.
Can You Use Soft Water in a Pool?
While it may seem like soft pool water would be ideal, the answer isn’t as straightforward as a simple “yes” or “no.” Softened water can be used in a pool, but it must be carefully managed to prevent damage to pool equipment, pool plaster, and tile grout. Let’s take a look at the advantages and disadvantages.
Benefits of Using Soft Water in a Pool
- Reduced Scaling and Mineral Buildup
Hard water often leads to calcium deposits along pool walls, ladders, and metal components. By using softened water, you can significantly reduce scaling, making pool maintenance easier and prolonging the lifespan of your pool equipment. - Gentler on Skin and Hair
Hard water can be harsh on your skin, causing dryness and irritation. Pool owners often notice that soft pool water feels silkier and is less likely to leave a filmy residue on the skin or hair. - Improved Water Clarity
Excess calcium in hard water can make pool water appear cloudy. Soft water, when properly balanced, can result in clearer, more inviting water, especially in fresh water pools.
Risks of Using Soft Water in a Pool
- Potential for Corrosion
While hard water can cause scale buildup, soft water that lacks calcium can become corrosive, which may damage pool plaster, concrete surfaces, metal surfaces, and metal components like ladders and handrails. - Difficulty Maintaining Proper Water Balance
Pool chemistry requires a delicate balance. Softened water lacks the necessary calcium hardness, which can make it challenging to stabilize pH and alkalinity levels. This could lead to fluctuations that require frequent monitoring and adjustments over time. - Increased Sodium Levels
Since most water softeners use sodium ion exchange to replace calcium and magnesium, softened water has higher sodium content. While not harmful for swimming, excess sodium can interfere with pool chemistry and some saltwater chlorine generators.
Best Practices for Using Soft Water in Your Pool
If you decide to fill your pool with softened water or partially soften your pool water, follow these best practices to maintain a safe and well-balanced swimming environment:
- Test Your Water Regularly
A reliable pool water test kit should be used frequently to check water chemistry.
Key factors to monitor include:
- pH levels (ideal range: 7.2-7.6)
- Total alkalinity (80-120 ppm)
- Calcium hardness levels (200-400 ppm)
- Chlorine levels (1-3 ppm)
- Maintain Proper Calcium Hardness
If your water is too soft, adding a calcium hardness increaser will help prevent corrosion and keep your pool plaster intact. Most pool supply stores carry calcium chloride or calcium hypochlorite products for this purpose.
- Partially Use Hard Water
One approach is to mix softened water with hard water. If your home has a bypass option on the household water softener, consider filling part of the pool with softened water and the rest with unsoftened city water to achieve a balanced mineral content.
- Monitor Salt Levels if Using a Saltwater Pool
If you have a salt water system, be mindful of sodium levels when using softened water. Too much sodium can throw off the efficiency of your salt water chlorine generator and impact chlorine production. - Adjust pH and Alkalinity as Needed
Because soft water can lead to lower pH and alkalinity, using alkalinity increasers or pH increasers may be necessary to stabilize the water and prevent damage to pool components.
Using softer water in your pool can offer several benefits such as reduced scaling and a more pleasant swimming experience, though it’s essential to be mindful of its potential risks related to corrosion and water balance. To ensure a healthy and enjoyable pool environment, regular testing and proper water management are crucial. If you’ve been considering making the switch to softened water, why not give it a try? Just be sure to remain vigilant about monitoring your pool’s chemistry! Take the step today towards a clearer, gentler pool experience and dive into your next swim with confidence.
