GoGreenCube gives discarded disposable hand warmers a new purpose as a water purification medium. The cube releases iron ions that bind with hydrogen sulfide and phosphate to form harmless iron sulfide and iron phosphate, reducing sludge, odors, and nutrient overload while supporting aquatic plants and seaweed. Each 100‑gram unit is intended for direct use in ponds, lakes, or coastal areas to restore clarity and ecosystem balance.
