Tetra Pond SludgeRemover breaks down organic sediment and substances such as plant remains or food residues in ponds. The biological action of the microorganisms in the product naturally cleans the pond and prevents the formation of large amounts of sediment. This reduces the need for time-consuming cleaning, which could disrupt the ecosystem. As this is a liquid product, it can be distributed throughout the garden pond extremely evenly. This makes Tetra Pond SludgeRemover a reliable and safe water care product for all pond fish.
