The Aqua One Plant Weight 6cm is a set of soft, malleable lead strips designed to anchor live or artificial plants to the substrate in freshwater aquariums. These 10 flexible weights securely hold plants in place, preventing them from floating as they establish roots or in tanks with active or strong fish. Each weight can be gently bent around the base of plant stems and trimmed to size if needed. With a safe, aquarium-friendly design, the Aqua One Plant Weight 6cm kit offers a simple and effective way to maintain a tidy and rooted aquascape.
