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.
