If you need help with that, our pool calculator would greatly help you.</li> <li>Next, measure the current salt concentration in ppm. Any standard chlorine generator will give you the reading.</li> <li>Finally, specify your desired concentration of the swimming pool salt in ppm.</li> <li>If the current ppm levels are lower than the desired levels, the pool salt calculator will show you how much more salt you need to add.</li> <li>On the other hand, if the current ppm levels are higher than the desired levels, then the salinity calculator will show you how much water you need to replace. This means that you need to drain out a specific amount of pool water and replace it with fresh water to bring down the salt concentration.</li> </ul> <script>const FRAME_ID = "toolpress-frame-168";</script><script>(function(){function sendHeight(){var h=Math.max(document.documentElement.scrollHeight,document.body.scrollHeight,document.documentElement.offsetHeight,document.body.offsetHeight);parent.postMessage({type:'toolpressEmbedHeight',id:FRAME_ID,height:h},'*');}window.addEventListener('load',sendHeight);window.addEventListener('resize',sendHeight);document.addEventListener('input',function(){setTimeout(sendHeight,50);});document.addEventListener('click',function(){setTimeout(sendHeight,50);});setTimeout(sendHeight,60);setTimeout(sendHeight,300);setTimeout(sendHeight,900);})();</script></body></html>
