EHEIM AKTIV 140g ≈ 250ml filter media

Active filter carbon designed for exceptional performance, particularly following the use of medications. EHEIM AKTIV is treated with acid washing and activated for optimum water absorption, featuring an impressive active surface area of 1200 m²/g. This allows it to swiftly capture and hold harmful chemicals, including pesticides and medication residues, resulting in crystal-clear aquarium water. Its application is especially crucial after administering treatments to the aquatic life. EHEIM AKTIV should be employed for a limited duration (approximately 4 weeks) before being removed or replaced. When setting up your filter layers, place EHEIM AKTIV directly after the mechanical (such as EHEIM MECH or MECHpro) and biological filter media (like EHEIM SUBSTRATpro) using the provided net bag. - Active carbon for self-activating adsorption - Quickly captures chlorine, pesticides, and other harmful chemicals - Ideal for use after setting up a new tank or following medication treatments - Recommended for limited use (around 4 weeks) - Suitable for both freshwater and marine environments Tip: It's advisable to use adsorptive filter media for a few weeks only, as harmful substances are merely attached and may detach over time, reintroducing them into the water. Regular changes are essential. Typically, adsorptive filtration is necessary only during the initial aquarium setup or after medication treatments. - Mechanically: No - Biological: No - Absorptive: Yes - Chemical: No - Net bag: No - Freshwater: Yes - Sea water: Yes - Width: 60 mm - Height: 141 mm - Depth: 59 mm - Packing: 6 Part(s)
