How To Lower Chlorine In A Salt Water Pool 8 Steps

If you turn off the machine, be sure to test the water 2-3 times per day, and turn the machine back on when the chlorine drops below 3. 0 ppm.

With no cyanuric acid (CYA) in the pool up to 90% of the chlorine can evaporate in as little as 2 hours on a hot, sunny day, so be sure the level doesn’t drop below 1. 0 ppm.

You should be able to find these chemicals at pool supply stores and online.

Submerge a tube in the pool and allow it to completely fill up with water. Plug 1 end of the tube and transfer it to an empty container at a lower elevation than the pool. Unplug the end of the tube and allow it to drain into the container. Pull the tube out of the pool when you’ve siphoned enough water. [6] X Research source

Make sure you’re testing free chlorine, not total chlorine, as the free chlorine is what is available to kill germs and bacteria in the water. Follow the specific directions including with your test strips or kit.
