Eheim Pickup 45 Internal Filter: Engineered for Optimal Mechanical Filtration in Compact Aquariums

The Eheim Pickup 45 operates on a fundamental yet effective single-stage mechanical filtration principle. Water is drawn into the unit by a 5-watt centrifugal pump, precisely rated for a maximum flow of 180 liters per hour. This fixed flow rate is engineered to provide continuous, gentle circulation suitable for small to medium-sized freshwater aquariums (20-45L), preventing excessive current which can stress smaller inhabitants or disrupt planted substrates. Filtration is exclusively achieved through the included sponge media, specifically designed to trap particulate matter such as detritus, uneaten food, and suspended debris, thereby enhancing water clarity. The 'Pickup' design inherently implies an accessible media cartridge, simplifying the removal and cleaning of the sponge without disturbing the entire filter body. While this filter excels in mechanical particle removal, it does not incorporate dedicated biological or chemical filtration stages, implying that supplemental biological filtration or appropriate tank cycling protocols are crucial for nitrogen cycle management. The 5W power consumption is notably low, offering an energy-efficient solution for continuous operation. Its auto-restart feature is a critical engineering detail, ensuring the pump automatically resumes function after a power interruption, preventing prolonged periods of unfiltered water. The absence of adjustable flow or self-priming capabilities underscores its design as a straightforward, 'plug-and-play' internal unit focused on reliability and core mechanical filtration.
