Brilliant lighting and outstanding plant growth, the modern MultiLux LED lighting technology from JUWEL offers. The replaceable 31 Watt LED tubes MARINE and BLUE produce an optimal light spectrum with a simultaneous energy saving of up to 50% compared to T5. The MultiLux LED illumination system of the RIO 450 LED allows comfortable working in the aquarium even when the lighting is switched on. The ultrasonic-welded luminaire is 100% watertight and meets the high European safety standards.
For optimum filtering, the RIO 125 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 500 circulation pump.
The 100 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 125 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.
With the matching base cabinet, your aquarium will stand safely on solid ground. The two of them also make the perfect pair from a visual point of view, as the base cabinet is available in the same colour as the aquarium. Easy to assemble with generous storage space for accessories and equipment, they also leave nothing to be desired from a practical point of view.
In fact, all that is left for you to do is simply to enjoy your beautiful style accessory every day!
