Keep your water butt fresh and odour free with this natural treatment. It uses beneficial bacteria to break down organic matter while staying completely safe for plants, pets and wildlife. A UV blocker reduces algae growth, while a flocculating agent clumps debris together so it sinks to the bottom. The result is clearer rainwater that’s ready to use in your garden all year round.
