Salt Required
Required salt to reach target salinity.
Common sizing for most stores in the United States.
Standard package size in Canada, UK, and Australia.
Safe Dissolving Advisory: Pour the salt bags directly along the deep end perimeter of your pool. Turn on your primary filter pump and brush the salt heaps until they are completely dissolved. Maintain circulating currents and keep your salt cell chlorinator turned off for 24 hours while the salt disperses to avoid low/high voltage spikes.
Keep your Krystal Clear generator producing chlorine without error codes 91 or 92.
Intex Salinity Thresholds & Error Codes
Intex saltwater generators continuously monitor salinity through titanium sensor plates. If salt drops below 2,500 PPM, the unit triggers error Code 91 (Low Salt) and ceases chlorine production to prevent electrolytic damage.
If salt exceeds 3,500 PPM, error Code 92 (High Salt) flashes and the system shuts down to protect its internal power supply. The only remedy for Code 92 is partially draining pool water and replacing it with fresh tap water.
