Adding salt to your swimming pool is an important step in maintaining its chemistry, especially if you own a saltwater pool. When done correctly, salt helps generate chlorine, keeping the water clean and safe. Incorrectly adding salt can lead to imbalanced water, which may cause discomfort or even damage the pool equipment.
In this guide, well discuss how to add salt to pool properly, ensuring the best swimming conditions. Whether youre a new pool owner or looking to refine your pool maintenance skills, this article will help you achieve the perfect balance.

Why Is Adding Salt to Your Pool Important?
Salt in a saltwater pool serves as the base component for the chlorine generator, which converts salt into chlorine through electrolysis. Maintaining the right pool salt level ensures proper disinfection and prevents algae growth.
How Much Salt Does Your Pool Need?
Before adding salt, it’s crucial to determine how much your pool requires. Most saltwater pools function best at a salt level of 2700-3400 ppm (parts per million). Check the chlorine generator manual to find the ideal salt concentration for your system.
Calculating the Right Amount of Salt
You need approximately 50 lb of salt per 2000 gallons of water to reach the desired concentration. Use a pool salinity calculator or consult a professional to double-check your calculations.
Choosing the Best Type of Pool Salt
Not all salt is suitable for swimming pools. You should use pure pool salt to prevent impurities from entering your water system.
Types of Salt to Use
- Solar salt: Naturally evaporated seawater, available in high-purity forms.
- Mechanically evaporated salt: Processed to remove contaminants, making it an excellent choice.
- Rock salt: Not recommended since it contains high amounts of impurities.
Step-by-Step Guide on How to Add Salt to Pool
1. Test the Current Salt Level
Use a salt test kit or a digital salinity meter to measure your pools current salt concentration. This ensures you add the correct amount.
2. Turn Off Your Salt Chlorine Generator
Before adding salt, turn off the pool system to prevent the generator from running while the salt is dissolving.
3. Pour the Salt Evenly Around the Pool
Broadcast the salt across the surface of the pool to ensure even distribution. Avoid dumping it in one spot.
4. Brush the Salt to Help It Dissolve
Use a pool brush to help speed up the dissolving process by spreading the salt along the pool floor.
5. Keep the Pump Running
Run the pool pump for at least 24 hours to mix the salt completely. This allows it to circulate thoroughly.
6. Test the Salt Levels Again
After full circulation, test the salinity levels again to ensure the concentration is within the recommended range.
Common Mistakes to Avoid When Adding Salt
- Adding too much salt without testing first.
- Using wrong types of salt that contain contaminants.
- Not allowing enough time for the salt to dissolve properly.
Maintaining the Right Salt Levels in Your Pool
Regular maintenance is necessary to ensure the ideal salt concentration. Check your pools salt levels at least once a month and after heavy rain, water drains, or seasonal changes.

Frequently Asked Questions (FAQ)
1. Can I Use Regular Table Salt in My Pool?
No, only pool-grade salt should be used to prevent impurities from affecting water chemistry.
2. How Often Should I Add Salt to My Pool?
Check salt levels monthly and add more when needed, especially after water loss due to backwashing or heavy rainfall.
3. What Happens If Pool Salt Levels Are Too Low?
If salt levels are too low, the chlorine generator may not produce enough chlorine, leading to algae growth and poor water quality.
