How to Add Salt to a Saltwater Pool
Home / Pool Care Tips /
Adding salt to a saltwater pool is necessary to keep the salt chlorine generator or salt cell working properly and to keep the water clean and balanced. Starting fresh or adding more salt to your pool is simple, whether you’ve just converted a chlorine pool to salt, have a new saltwater pool that needs to be filled, or just need to add more salt to a pool you already have. However, it must be done correctly to avoid problems like scaling or low chlorine production. Here is a quick guide on how to add salt to a saltwater pool correctly, the different types of pool salt available, and saltwater pool maintenance tips to keep your saltwater pool running smoothly.
About the Pool Salt
What is Pool Salt?
Pool salt is high-purity sodium chloride and is made especially for use in saltwater pool systems. It doesn’t contain the iodine or anti-caking agents found in regular table salt, which can cause issues with pool equipment. Pool salt is dissolved in the pool water, where it passes through a salt chlorine generator to produce chlorine. This device converts dissolved salt in the water into chlorine through electrolysis, which helps sanitize the pool and keep it free of harmful bacteria and algae.
Why Adding Salt to a Saltwater Pool is Important

Salt is the foundation of a saltwater pool. It helps to generate Chlorine, which keeps your pool free of harmful bacteria and algae. Unlike traditional chlorine pools, where Chlorine is added manually, a saltwater pool generates Chlorine from a salt chlorine generator, Which provides consistent chlorine production, reduces chemical usage, and offers cost-effective maintenance and also gentler on sensitive skin and eyes, providing a smoother, more comfortable water feel compared to traditional chlorinated pools, reducing the need for manual chlorine addition. You can read our blog on salt pool vs chlorine pool. It provides a detailed comparison of both types, covering aspects such as maintenance, costs, water quality, and overall benefits, helping you make an informed choice.

How to add salt to pool
Adding salt to a saltwater pool requires careful steps to get the right salt levels for proper chlorine production. Be careful not to add too much or too little. Low salt levels in a saltwater pool can lead to issues such as low chlorine levels, cloudy water, increased chemical usage, skin irritation, pool equipment damage, and unbalanced water chemistry. On the other hand, High salt levels can speed up corrosion of metal components of pool equipment, damage salt cell, and cause unsightly calcium deposits on pool surfaces and plumbing. Excessive salt can mess up Pool chemical balance, leading to low chlorine production.
7 steps to add Salt in Pool
Step 1: Test Pool Salt Levels
Before adding any pool salt, the first step is to test your pool’s current salt levels. This can be done using a pool salt test kit or a digital salt meter. The ideal pool salt level range for most saltwater chlorinators is between 2700 and 3400 ppm (parts per million). If you are adding salt to the pool for the first time, it’s important to calculate your pool’s water volume accurately. Knowing the pool’s volume allows you to determine the exact amount of salt needed to reach the desired salt level, avoiding the risk of over or under-salting. Make sure your pool’s filtration system is running when you take your sample to get the most accurate reading.
Testing salt level with different kits
Salt Test Strips:
Dip a test strip in water for a few seconds, then remove and wait for 15-30 seconds. Match the strip’s color to the chart on the container or package, aiming for a salt concentration between 2,700 and 3,400 ppm. If below, add more salt or dilute water.
Tips for Accurate Reading: Avoid dipping the strip near return jets or skimmers, as this may give inaccurate readings. Use the strip immediately after opening, as exposure to air can impact accuracy.
Digital Salt Meter:
Digital Pool Salt Meter
Submerge the Probe: Dip the probe end of the meter about 2 inches below the water surface, avoiding air bubbles and debris. Hold the meter in the water until the reading stabilizes on the display. The meter will show direct ppm reading of the salt level.
Tips for Accurate Results: Rinse the meter with distilled water after each use to prevent residue buildup. Store the meter in a dry place out of direct sunlight.
Step 2: Calculate How Much Salt Your Pool Needs
Always know how many bags of salt you’ll need to get the ideal pool salt level, which is usually between 2700 and 3400 ppm before you start using it. You can use a pool salt calculator or do a simple calculation to find out how much salt is needed to start a pool or change the salt level in an existing pool.
Using a Pool Salt Calculator: You can get a good idea of how much salt you need by entering the size of your pool, the level of salt that’s already in it, and the level of salt that you want it to have. This will help you a lot if this is your first time adding salt.
As an example, you would need about 100 pounds of pool salt if your pool has 15,000 gallons and you wish to reach a level of 3200 ppm. To maintain the proper range, always use pool-grade salt and test your pool’s salt levels on a regular basis.

How to Choose the Chemicals When We Are Cleaning Our Pools
Choosing the right chemicals for your pool cleaning service is essential for maintaining a clean and safe swimming environment.
First, we can research for local chemists who specialize in pool care and have a good reputation. If he has the certifications and has engaged the pool care for a long time, we can ask about the questions about water balance and safety.
Additionally, consider asking for recommendations from experienced friends or checking online reviews to get information about the chemicals. It’s also beneficial to inquire about the function of these chemicals and whether they suit our pool, so choosing the chemicals is the important part of pool cleaning.
How Often Should You Clean Your Pool?
How Often Should You Clean Your Pool?
1. Daily Tasks: Skim and Check
- Skim Debris: Remove leaves, insects, and floating debris daily using a skimmer net. This prevents clogs and maintains water clarity .
- Check Water Levels: Ensure the water level stays midway up the skimmer opening to maintain proper filtration.
