If you have a pool at home or are going to build a new swimming pool for personal or business use, then you should know how much sodium chloride (NaCl) or salt is required for the proper salinity of the pool. You can calculate pool salt level based on pool volume and other options with the help of 5 free online pool salt calculator websites.
There could be many reasons when you need to calculate the recommended level for pool salt. If the amount of salt is less or more in the pool, then the salt chlorine generator of your pool can remind you that it cannot produce the required amount of chlorine or you may have dried the pool and need to add salt again after filling the water. PPM salt (parts per million) or salt level should be at the recommended level (usually 3200 ppm). Having said that, these sites are great to use.
Here are 5 free online pool salt calculator websites for Calculating Salt Levels in Pools:
Hayward-pool
Hayward-pool is one of the best options for calculating pool salt. You can visit this site from here. Like the Pentair Pool Salinity Calculator (mentioned below), it also shows how many lbs of salt it would take to raise the salt level to the recommended level (i.e. 3200 ppm). The output is based on the pool size or volume and the current salt reading. Both the pool size and the current salt reading can be set using separate sliders.
It has several other interesting features that make it better than many other salt pool calculator sites. These features include:
- Check the ph level of the pool water to find out if the ph level is normal or acidic.
- Find the total alkalinity in the pool water.
- Find out if the cyanuric acid level is normal.
- Check the total amount of minerals in the pool water. Calcium hardness is calculated to get the result.
For each of these options, you can use the slider to set the current level, and based on that you will get the result.
Poolchemicalcalculator
Poolchemicalcalculator is one of my favorite pool salt calculators. This website is useful for finding the desired salt PPM based on the current salt PPM and pond volume in gallons. The good thing is that it also lets you calculate pool salt for pools over 20k gallons.
Here, you need to be careful not to show the recommended pool salt. Instead, you need to provide the desired salt PPM and current salt PPM and then it will suggest you the number of salt bags and total sodium chloride needed to get the salt PPM you specified. So, it works in a slightly different way than other salt pool calculator sites.
Another feature I like is that there is a slider available to set the pool gallons, required salt PPM, and current salt PPM. When the input is ready, press the Calculate button. After that, the number of salt bags will be displayed with the recommended lbs of sodium chloride needed for the desired salt PPM.
Pentair Pool Salinity Calculator
Pentair Pool Salinity Calculator is a simpler website. You can visit this site from here. There are only two sliders. You just need to drag that slider to set the available or current salt level and pool volume. As soon as you enter these two inputs using the slider, a salt request is provided. Salt demand or recommended amount of salt is given in lbs and kilograms.
This is all we can do on this website for pool salt calculation. This site does not provide any other options. This is an easy option to quickly calculate the recommended pool salt content.
Salt Calculator
Salt Calculator ( homepage ) is also a good option to find out the salt needed to raise the amount to the required level (3200 ppm) or the salt 4000 ppm. You can enter the pool volume in US gallons, salt level, cost of salt per 100 lb (in US dollars), and it will then give you the result. The feature to add salt cost is also rare which is not available on other pool volume calculator sites.
Based on the input value, you will see the calculated result for the salt level. If you have entered the cost of salt per 100 lb, then you can also get an estimate of the cost of salt required. This website has a very simple interface but the options are great to use.
Direct Salt Addition Calculator
Direct Salt Addition Calculator is the last website on this list. This website is also quite good for knowing the approximate volume of salt needed and the weight of salt required. For an estimate of the volume of salt required, the results can be seen in US gallons, cubic feet, cubic meters, cubic centimeters, cubic inches, etc. And for the required weight of salt, the result can be seen in US pounds, grams and kilograms.
You can enter water volume in US gallons, liters, cubic feet, cubic inches, etc., set current salinity level, target salinity (must be higher than current salinity), water temperature (in kelvin, Fahrenheit, or Celsius), water impurity in the salt mixture, and then calculate the approximate volume of salt and salt weight required.
Conclusion: These are the 5 best online pool salt calculators that you can try. Since the recommended or required salt levels based on pool volume are generated by all sites fairly well, they are all useful. However, based on different features, you can check which one helps you the most. Safespedia sees first website better than others as it also lets you check ph level, total alkalinity, calcium hardness in pool water, etc.
