You purchased a mineral sanitizing system because you wanted an alternative to your chlorine tablet, saltwater, or bromine system.
You're looking for softer skin, softer water, less harm to your equipment.
One misconception is whether you still need a sanitizer, and you do.
So, in short - Sutro does work with mineral systems. Because we measure chlorine in true PPM (parts per million) and not mV (millivolt). We're able to turn down the volume on your chlorine consumption.
When setting up your pool or spa profile select the optional sanitizer mineral in order to adjust the Sutro settings.
