Experience top-notch filtration technology with the integrated features of the professionel 4+, the latest evolution in our line of external filters. Its square canister design provides stability, accommodates a generous filter volume, fits neatly in corners, and saves space. The innovative Xtender function allows for longer intervals between filter cleanings. The professionel 4+ is offered in three sizes, catering to aquariums of 250, 350, and 600 liters. Additionally, the 250 and 350 models are available as thermo filters (T). All professionel 4+ filters are known for their impressive flow rate, energy efficiency, and added features: Self-priming: Eliminate complicated suction techniques! The self-priming aid prepares the filter system for a quick and effortless start. Safety hose adapter: The tap unit comes equipped with two hose connectors. For safety, the hose adapter can only be detached when the valves are closed. Prefilter: The upper prefilter captures larger dirt particles and can be regularly cleaned, extending the maintenance period between media cleanings. Filter baskets: Unique filter baskets for biological and mechanical media can be easily removed, with the contents easily cleaned using the ‘Easy Clean’ grid. “Xtender” Control Function: If the media (fine filter pad) becomes clogged, the flow rate can be increased through the control function. This allows water to be redirected while maintaining biological filtration, postponing the need for filter cleaning by a few days. Quiet operation: EHEIM’s high-performance bearings and ceramic axles ensure silent operation, longevity, and reliability.

With the EHEIM biopower, you have access to a high-performance internal filter that is truly innovative. It features a fully rotatable pump head, modular design, and additional functionalities derived from the aquaball concept. What sets the biopower apart is its multilayer filtration system, similar to that of an external filter. The enclosed filter baskets are filled with highly efficient filter media (such as SUBSTRATpro). Located at the bottom is the inlet basket, which contains a filter cartridge for mechanical-biological prefiltration. Water is drawn in from the bottom and pumped upwards through various filter layers, returning to the aquarium after filtration. There are three models available for aquariums ranging from 80 to 240 liters. The aquaball concept employs external filter technology and multi-layer filtration, which means that water is pumped from the bottom to the top through several filter layers before it is returned to the tank. The closed filter baskets come prefilled with EHEIM SUBSTRATpro, although other filter media can also be utilized. The inlet basket incorporates a filter cartridge for mechanical-biological prefiltration, while a filter pad in the pump head holder provides an extra layer of filtration. You can adjust the filter volume as needed by adding or removing filter modules (filter baskets). To extend the filter's capabilities, consider the ExtensionSET2. The filter baskets are designed for easy assembly and disassembly, thanks to the Easy-Klick Locking System. The modular design allows for cleaning of filter cartridges or media at varying intervals, helping to maintain beneficial bacteria cultures. The ball-shaped pump head sits in a ball socket, allowing it to be rotated freely. This flexibility means that the outflow of filtered water can be directed in any desired direction. The pump output and flow rate can be adjusted using the control knob located on the outflow nozzle. The power-diffuser can be modified to regulate air intake, enhancing oxygen levels in the aquarium. (Alternatively, other extension pieces can be utilized; see accessories for options.) The holder for the biopower is easily attached to the glass with suction cups. For maintenance, module changes, or adding filter media, the filter can be quickly removed from its holder. For outdoor use: No For aquariums of about: 80 Liters For aquariums up to approx.: 160 Liters Pump power (50 Hz) per hour of approx.: 180l - 550l Pumping head approx.

EHEIM bioMECH Mechanical-biological filter medium for comprehensive water treatment bioMECH has been ingeniously crafted: its dirt-trapping pockets effectively capture and hold both large and small dirt particles. Simultaneously, the intricately designed pore structure allows for the colonization of purification bacteria, ensuring efficient biological decomposition. The material is pH-neutral and free from water hardeners. EHEIM bioMECH is designed to be washed and reused multiple times. - Specifically formulated filter medium for concurrent mechanical and biological water purification - The material is pH-neutral and does not contain water hardeners - Can be reused (gently wash to preserve the bacteria cultures) In general, mechanical filter media are adept at capturing larger dirt particles, while biological filter media create ideal conditions for bacteria cultures to thrive: these purification bacteria consume the dirt particles and transform them. This process ultimately leads to clear, healthy water and stable water parameters in your aquarium. Our latest innovation is a dual-function filter medium that performs both mechanical and biological tasks simultaneously. - Mechanically: Yes - Biological: Yes - Absorptive: No - Chemical: No - Net bag: No - Freshwater: Yes - Sea water: No - Width: 140 mm - Height: 177 mm - Depth: 73 mm

EHEIM SUBSTRAT Standard bio-filter medium featuring a vast colonization area for beneficial bacteria and exceptional efficiency. SUBSTRAT can be arranged in one or multiple layers. This filter material is highly porous and crafted from sintered glass. Its unique surface structure provides optimal conditions for the essential purification bacteria to thrive. The available colonizable area is an impressive 450 m² per litre. EHEIM SUBSTRAT is washable and can be reused. Standard bio-filter medium Highly porous material made from sintered glass Excellent conditions for bacteria cultures Reusable (rinse gently to clean) The primary function of biological filter media is to create the ideal conditions for bacteria cultures, allowing a thriving bacteria lawn to develop in a short period. These bacteria consume various dirt particles and transform substances that could be harmful to your aquarium. After the initial cleaning phase conducted by mechanical filter media (such as EHEIM MECH or MECHpro), biological filtration becomes crucial. It ensures clear, healthy water and stable water parameters. This is why we have dedicated significant research efforts to the advancement of biological filter media. Tip: Avoid cleaning or replacing all filter media simultaneously (and refrain from overly aggressive cleaning). It's crucial to preserve the bacteria cultures; otherwise, the re-colonization process will be delayed. The filter baskets in external filters and filter modules within internal filters like aquaball and biopower are perfect for partial cleaning.
