20Kg PoolPro Ultrafine Pool Salt

A high-purity, ultrafine-grade pool salt made for saltwater chlorinators. The salt dissolves into the water where your chlorinator converts it into chlorine to keep the pool sanitised. Add it when first setting up a salt pool or to top up the salt level after rain, backwashing or dilution. Broadcast it over the water and let it dissolve, ideally with the pump running.
