The Juwel filter system offers one of the largest filter volumes of any aquarium filter in its class. Designed in Switzerland by fish keepers for fish keepers, it offers an easy to use system that is contained within the aquarium. There are no external pipes to restrict flow or leak, and maintenance is taken care of using the clever basket system.

Juwel Pumps are optimised for the size of the aquarium's filtration system. Often smaller than you might expect, they give the correct amount of flow for the filters to work efficiently. Slower circulation of water through the media provides optimum conditions for cleaning the aquarium water. The filter bacteria require sufficient contact time with the water to be cleaned.

Increased circulation can produces less effective filtering! Also, an increase in water movement expels the most important plant nutrients (should you have a planted aquarium). For good plant growth, please do not use additional aeration.

To conclude: the more slowly the water flows through the filter, the more effective the cleaning. Optimum circulation only occurs as a result of large cleaning intervals. Vigorous water movement and aeration damage plant growth.

The Juwel Pump 1000 has a capacity of approximately 1000 litres per hour. The pump will fit into all JUWEL Filter Systems except the Filter System Compact Super.
