1 piece Activated carbon filter, aquarium water purification, honeycomb 10x10x10 cm, for fish and reptiles

This single-block activated carbon filter is specially designed for supplemental water purification in indoor aquariums. Its honeycomb structure provides an extensive adsorption surface, ideal for capturing dissolved organic compounds, drug residues, yellowing, and unpleasant odors. Each 10.0 x 10.0 x 10.0 cm cube is made from activated vegetable carbon, rigorously tested for its ash content (< 5%) and chemical stability. It installs without tools in the filter chamber or filter basket, upstream of the pump—a strategic position to maximize water-carbon contact. Compliant with European REACH regulations for products intended for pets, it does not alter the water's physicochemical parameters (pH, hardness, conductivity) and is suitable for both community aquariums and mixed aquatic terrariums.
