Pure copper bird bath disk (0.6 mm) that improves water quality and reduces maintenance by slowly releasing copper ions. Key benefits Fewer cleanings: Copper ion release helps limit algae and bacterial growth, extending cleaning intervals from about every 3 days to around 20 days. Safe for birds: Made and tested for safety with all bird species. Provides a cleaner bathing environment without chemicals or added treatments. Reliable, longlasting performance: Pure copper construction and a reinforced support design maintain shape and function season after season. What makes this different Material and thickness: Crafted from pure copper, 0.6 mm thick for consistent ion release and longterm durability. Stable support design: The innovative triple point support structure keeps the disk level, resists deformation, and maintains water surface contact for steady performance. Weatherproof for yearround use: Built to withstand sun, rain, and snow. Compatible with heated bird baths in winter so you do not need to remove it seasonally. Key features Function: Gradual copper ion release to reduce microbial and algal growth and keep water fresher between cleanings. Compatibility: Appropriate for use in outdoor bird baths, including heated units used in winter months. Durability: Corrosionresistant copper construction designed for repeated outdoor exposure and frequent use. Use scenarios Backyard bird bath: Place the disk in a garden bath to cut down on algae growth and reduce how often you need to empty and scrub the basin. Community or park birding stations: Lower maintenance frequency in shared or hardtoservice baths while maintaining a safer bathing environment for many species. Winter heated baths: Keep the disk in place with a heated unit to maintain water quality through cold months without seasonal removal. Notes No added chemicals required. Follow standard bird bath cleaning practices as needed.
