Resinguard or Superior Crystal High Quality Salt Pellets - Available in store only
ResinGard® Water Softener Salt Pellets are designed to remove various raw water contaminants that become entrapped in the softener mineral bed, thereby reducing its softening capacity. ResinGard® brand contains two surface active agents (surfactants) which effectively remove contaminants from the resin bed and allow them to be flushed away in the rinse cycle of the softener regeneration. The uniform size and density of this pillow-shaped, compressed, high purity evaporated salt pellet minimizes bridging or channeling to provide excellent percolation under normal use and the food grade additive Sodium Hexametaphosphate is added to the salt before compaction as a hardening agent to minimize pellet mushing.
Superior Crystal Salt Pellets have the same specifications without any additives.
