Maintain a pristine bird bath effortlessly with the 99.99% Pure Copper Bird Bath Cleaner Disc. This innovative solution leverages copper's natural properties to keep water fresh and significantly reduce cleaning frequency. Its 0.6 mm thick, pure copper construction features an effective 3-point support design for maximum water contact, working continuously to inhibit slime and green growth. Compatible exclusively with non-metallic basins like stone, plastic, nylon, or composite materials, it prevents the metal reactions that neutralize efficacy. Experience extended cleaning intervals from every 3-days to approximately every 14-days, saving you around 120 minutes of cleaning time and about $200 annually on cleaning tools. The disc undergoes a special all-weather passivation process, ensuring consistent physical purification performance year-round without interfering with fountains or heaters. A deeper weekly or bi-weekly cleaning is still recommended for optimal hygiene. This patented design is a reliable, money-saving investment for any bird lover.
