High-performance internal filter system with a large filter volume and easy maintenance. Excellent filtration thanks to the double flow principle. Ideal flow and integrated heater provide maximum safety. Maximum pump performance: 1000 l/h. Compatible with Rio 450 LED, Vision 450 LED, Trigon 350 LED, and Rio 450 LED.

The JUWEL Bioflow internal filter system, scientifically tested multiple times by independent institutes, has long been one of the world's leading filter systems in modern aquaristics and has proven itself millions of times. It features an exceptionally large filter volume that allows for excellent mechanical, chemical, and biological filtration. This ensures long filter lifetimes and extended maintenance intervals.

The design of the filter allows easy access to the pump and heater, and the use of special filter baskets ensures easy removal and cleaning of the filter media. The unique double flow principle of the JUWEL Bioflow filter system enables different flow rates within the filter, significantly contributing to its exceptionally high filtration performance. In particular, a relatively fast flow rate in the upper filter area is advantageous for mechanical and chemical filtration, while a slower flow rate in the lower part of the filter promotes the optimal development of anaerobic bacteria, which are essential for biological filtration.
