1. Juwel Aquarium EccoSkim
The Juwel EccoSkim combines the product advantages of a surface aspirator with a compact shape and a high, adjustable surface aspiration performance. With an output of 300l/h at a consumption of only 4.4W, the Juwel EccoSkim ensures effective surface suction in freshwater aquariums. The suction power of the Juwel EccoSkim removes in a very short time kahmhaut and other organic residues from the water surface. Without the formation of a film of water and other impurities, more light reaches the substrate, which increases the oxygen content and promotes the vitality of your plants and fish. The Juwel EccoSkim can be used in all Juwel aquariums. The filter suspension allows the EccoSkim to be easily attached directly to the Juwel internal filter. Impurities on the water surface are effectively sucked off and transported directly into the Juwel internal filter. The float of the Juwel EccoSkim adjusts to the water level and thus always has the ideal position for effective surface suction. The suction power of the Juwel EccoSkim can be regulated individually. By turning the regulating tube, the power can be influenced and thus adapted to the needs in the aquarium.

3. Juwel Aquarium Nitrax nitrate remover
The Juwel Nitrax reduces nitrate in your aquarium, leading to a significant decrease in algae growth. Nitrax is a biological filter medium and contains special microorganisms that break down toxic metabolic products (ammonium, nitrite) in your aquarium. This reduces the risk of fish mortality. Additionally, Nitrax reduces algae growth through the anaerobic breakdown of nitrate, thereby promoting the vitality of your fish.

4. Eheim Aquarium internal filter
The EHEIM Pickup is a small, practical filter with a unique concept. The filter can be easily attached to the tank using suction cups. What makes the Pickup's design special is that the filter canister along with the cartridge can be removed from the top while the pump unit remains in the tank. This is a very convenient solution for cleaning or replacing the filter cartridge. The pump draws water from the bottom and pushes it through the filter cartridge upwards. The filtered water is then directed back into the tank through the swiveling outlet nozzle.

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.
