Pool salt level measurement with SmartRef Digital Refractometer
Jun 14, 2023
Salt makes your live sweet and your pool fresh
It's important to keep an eye on pool salt levels and to check them periodically to see if adjustments are needed - but with SmartRef Digital Refractomer it has never been easier.
Like a holiday by the sea - relax at your saltwater pool
In recent years, also due to the corona-related retreat into privacy, setting up pools in the garden has become increasingly popular. Here the saltwater pool is a wonderful alternative to the traditional chlorine water pool. Although saltwater pools contain significantly less salt than the sea, they still give the feeling of swimming in the sea. The health aspects are also not to be despised: swimming in salt water has a positive effect on asthma and allergies - no annoying chlorine that irritates the respiratory tract and skin. The minerals found in salt water can help balance the skin's oil production and support the skin's barrier to retain moisture. In addition to the positive effects on the body, salt water also has a positive effect on the mind, helping to reduce stress and anxiety.
The optimum pool salt level
The ideal salt level for a saltwater pool is between 2.7 - 3.4 ppt (2700 - 3400 ppm), whereby the optimum level is 3.2 ppt (3200 ppm). At this level, the pool provides the health benefits listed above. However, if the amount of salt in the pool water is too high or too low, undesirable side effects can occur.
If there is too little salt in the pool water, not enough chlorine is produced which is needed to prevent the growth of bacteria and algae. In addition, too little salt in the pool is also a sign that the pool is loosing salt because of e.g. rainwater getting into the pool.
On the other hand, too much salt (5-6 ppt: 5000-6000 ppm) can attack and corrode the metal equipment in the pool. This might happen when you put too much salt in your pool or when high temperatures in the summer cause the water to evaporate and the salt to concentrate in your pool. In this case, the water must be diluted to reduce the salt content. When your pool is full, you need to partially drain it to add some fresh water.
You see, in order to maintain optimal pool water chemistry, it is necessary to measure the water salinity regularly.
Keep your pool intact - measure the salinity with the SmartRef Digital Refractometer
Use SmartRef to test the salt level when first filling the pool. Slowly add the salt to the pool and measure the salinity regularly to avoid dissolving too much salt.
SmartRef is also your faithful companion throughout the bathing season to monitor the correct salt content at regular intervals.
How often should you measure the salt level in your pool?
Measure the salinity in your pool:
- at least every month
- after intensive rain
- after heavy use
- after refilling fresh water to your pool
In just 5 steps to your measurement result
- Download the free Reef Meister app from the Google Play Store or Apple App Store.
- Activate Bluetooth on your smartphone or tablet.
- Switch your SmartRef on.
- Connect SmartRef with the app.
- Pipette only 0.4 mL of your pool water in the sample well and press measure. Within seconds the result is shown on the screen of your app in ppt (=ppm), SG 20/20, or PSU, as you wish.
If you are interested in documentation and if you like to log your measurements, just create a tank in your Reef Meister mobile app and store your measurement results in the tank. Results can also be graphically displayed over a period of time.
Checking the salt level for your saltwater pool couldn´t be easier!
