Long-Lasting Copper Algae Inhibitor for Fountains

Algae growth is a common and tedious problem for fountain owners, leading to constant cleaning and refilling. The community's suggestion of using copper indicates a market for a purpose-built, long-lasting copper product (e.g., a decorative copper insert, a slow-release copper puck) that effectively prevents algae without requiring constant attention, with clear guidance on safety for fish or plants.
