The EHEIM Professional 4+ 250 (2271) is an advanced external aquarium filter designed for hobbyists seeking powerful, efficient, and quiet water filtration. It enhances the proven features of the Professional 3 series with an innovative 'Xtender' button, allowing users to extend filter service intervals by redirecting flow when fine filter media is clogged, thus maintaining essential biological filtration. This filter is ideal for medium-sized aquariums, offering reliable performance and ease of use with its integrated priming aid and safety hose adapter, though initial setup may require careful attention to hose connections.

This filter is designed for freshwater aquariums with a volume of up to 250 liters.
The Xtender button redirects water flow around the fine filter media when it becomes clogged. This allows the filter to continue running efficiently for a longer period, preserving biological filtration until you can perform a full cleaning.
The filter typically comes with initial filter media. However, replacement media will be required over time, and you can choose specific media types to suit your aquarium's needs.
The filter includes a priming aid to simplify startup. While it involves connecting hoses and filling the canister, the instructions provided are detailed. It may require some patience for first-time users.
The frequency depends on your aquarium's bioload and stocking level. With the Xtender button, you can often extend intervals, but a general guideline is to clean mechanical media when flow is noticeably reduced, and biological media gently every few months.
The EHEIM Professional 4+ 250 is primarily designed and recommended for freshwater aquariums. Using it in saltwater may require specific considerations or compatible media not always included.
Please refer to the product manual or EHEIM's official website for the most current warranty information, as it can vary by region and retailer.
Ensure hoses are correctly connected and submerged. Check the priming aid is fully engaged. Verify the filter canister is sealed properly and filled with water.
Check that the filter is stable and not vibrating against aquarium furniture. Ensure all media baskets are seated correctly and that no air is trapped within the canister. Run the priming aid again.
Activate the Xtender button to temporarily restore flow and prolong the service interval. Schedule a cleaning of the fine filter media soon. Check inlet strainer for blockages.
Ensure the filter canister lid and seals are clean and properly seated. Check that all hose connections are secure and tightened correctly on the safety adapter.
