Built in Filtration and Heater

For optimum filtering, the RIO 240 LED is fitted with a high-performance Bioflow M. This internal filter combines efficiency with safety and forms the centrepiece of any JUWEL aquarium. It works on the principle that “The water should stay in the aquarium!” and is the safest way of filtering an aquarium. The Bioflow M comes fitted with five high-performance filter media and a quiet yet powerful Eccoflow 600 circulation pump.The 200 Watt JUWEL adjustable heater, which is perfectly embedded in the water circulation in the Bioflow M filter system, ensures the right temperature in the RIO 180 LED.Because it uses top-quality silver contacts and shock-proof borosilicate glass, JUWEL adjustable heaters meet the highest standards in both function and safety and, as you would expect, are TÜV/GS certified.
