Resist should always be added when a pool is initially filled or when fresh water is added, because most fresh water will contain some stain and scale producing minerals.
Filled pools should be circulated overnight before adding chlorine or other pool chemicals to allow resist to react with and prevent precipitation of minerals in fresh fill water.
