4 Critical Steps When Adding Salt to Your Pool
Salt does not evaporate. It only leaves via splash-out or backwashing. Never assume salinity is 0 until you test with a digital meter or test strip.
Turn your chlorinator generator power switch to OFF. High undissolved salt spikes can trip your cell's high-current protection board.
Scatter salt bags around the pool perimeter, focusing on the deep end. Immediately brush with a pool broom until no granules sit on the liner.
Keep the circulation pump operating continuously for 24 hours. Retest salinity, then turn your salt chlorine generator back ON.
Ensure long life for your salt cell by choosing fast-dissolving, high-purity salt crystals and reliable digital salinity meters.
