How to lower salt levels in a pool
Look at your pool's control panel for a quick salt level readout.
Most modern saltwater pools come with high-tech control panels that, among other things, allow you to check the water's overall salt levels. Control panels give this number in parts per million, or ppm, meaning you won't need to convert it.
Though convenient, control panels do not always function properly, making them more prone to inaccurate readouts. Dip a test strip in your pool water for a more accurate salt level readout.
