Eheim Aquaball 180: Precision-Engineered 3-Stage Internal Aquarium Filter

The Eheim Aquaball 180's filtration mechanism is engineered for superior water purification within its specified operating parameters. At its core is a powerful yet energy-efficient 10-watt centrifugal pump capable of delivering an adjustable flow rate up to 650 liters per hour (LPH). This flow rate is critical for maintaining healthy aquatic ecosystems, providing approximately 3.6 tank turnovers per hour for a 180-liter aquarium, ensuring efficient waste removal and oxygenation. The filter employs a robust 3-stage filtration system: * Mechanical Filtration: High-density filter sponges are utilized to physically remove particulate matter such as debris, uneaten food, and suspended algae. The strategic placement and volume of these sponges ensure effective trapping of micro-particulates, contributing significantly to water clarity. * Biological Filtration: Integrated bio-media provides an expansive surface area for the colonization of beneficial nitrifying bacteria. These bacteria are essential for the nitrification cycle, converting toxic ammonia and nitrites into less harmful nitrates, thereby maintaining critical water parameters. * Modular Design for Optimization: The Aquaball's unique modular basket system allows for flexible layering and easy access to filtration media, simplifying routine cleaning and media replacement while preserving established biological colonies. While specific noise level (dB) data is not provided, Eheim's reputation for precision engineering and high-quality pump components (plastic impeller) generally translates to exceptionally quiet operation, a significant advantage for internal filters positioned directly within the living space. The system's non-self-priming nature is typical for internal submersible units, requiring full submersion for operation. The 1.5-meter cord length and 220-240V/50Hz input voltage confirm its compatibility with standard European power grids, further solidified by its CE and RoHS certifications. Its compact footprint (110mm x 110mm x 250mm) and 1.1 kg weight ensure minimal visual intrusion while maximizing filtration capacity per unit volume.
