9. Fluval Fx6 3500l/H
The Fluval FX6 external filter features a multi-stage filtration system that allows for the precise stacking of filter media in the combination that is most suitable for the aquarium. This ensures unrestricted flexibility in creating and maintaining the ideal environment for fish. With its enormous capacity and powerful integrated motor, which circulates a full 2300 liters of water per hour, it enables precise adjustment of water properties in aquariums up to 1500 liters. It can hold up to 5.9 liters of filter media while remaining compact enough to fit in almost any aquarium cabinet. Thanks to Fluval's unique intelligent pump technology, the self-priming system requires simply plugging the filter into the power supply, and the filter starts automatically. It then fills with water, briefly pauses to release trapped air, and immediately begins the filtration process. Filtration continues until the unit is unplugged. Every 12 hours, the filter pauses to release any air that has entered the system, thereby maintaining the vacuum necessary for maximum efficiency. Additionally, the Fluval external filter includes a connection for refilling the aquarium.
10. Eheim Skim 350
The small surface film killer. In almost every aquarium, a film of microorganisms, dust, oils, and food fats forms on the water's surface over time - the surface film. With the EHEIM skim350 surface skimmer, you can reliably eliminate this film, achieving a crystal-clear water surface and higher oxygen levels. The EHEIM skim350, designed for continuous operation, is also suitable for short-term use. When used alternately in multiple aquariums, please ensure that no algae spores or diseases are transferred. The sucked-in bacteria and dirt particles accumulate in the filter sponge, which can be easily removed and thoroughly cleaned after use.
