Water Butt Klear is a revolutionary treatment that not only cleans your water butt but also improves nourishment for your plants. As the first product of its kind, it uses an organic blend of beneficial bacteria, including strains from our popular Pond Klear, to effectively target the organic matter that causes green water, unpleasant odors, and algae build-up.
Unlike traditional water butt treatments that rely on harsh sanitizers or disinfectants to kill bacteria, Water Butt Klear is a safe and non-toxic solution. While other treatments can introduce harmful chemicals into your soil, Water Butt Klear helps maintain healthy water without compromising plant health.
Once the bacteria in Water Butt Klear clear your water, they continue to work year-round, keeping your water clean and fresh. Additionally, the unique blend of bacteria promotes strong plant growth, boosts crop yield, and helps reduce plant diseases, offering a natural and sustainable way to care for both your water butt and garden.
