Welcome to hot tub water care, courtesy of Frog @ease. Set the dial on the Frog @ease SmartChlor Cartridge per the chart. Replace the Frog @ease SmartChlor Cartridge when the test strip shows it is empty and shock with Frog Maintain Non-Chlorine Shock. These are three SmartChlor refills only. These are the grey ones. No minerals or test strips are included. When the season ends (about every three months), please buy a new @ease System to get fresh minerals, test strips, and an additional SmartChlor cartridge.
