The JUWEL Rio range covers a wide spectrum of sizes to suit different needs and room sizes. The Rio 125 holds 125 litres and is a compact, stylish option for smaller spaces. The Rio 180 has a capacity of 180 litres and offers a balance between volume and footprint. The Rio 240 provides 240 litres of space and is ideal for medium to large aquascapes. For larger displays, the Rio 290, Rio 350, and Rio 450 models provide increased water volume and wider dimensions, giving you more flexibility with livestock and layout.

Each Rio model is equipped with a JUWEL Bioflow internal filter, which is built into the corner of the tank. The system varies by size: smaller models like the Rio 125 and Rio 180 use the Bioflow M, while the Rio 240 and Rio 290 use the Bioflow L, and larger models like the Rio 350 and 450 are fitted with the Bioflow XL. These filters offer mechanical, chemical, and biological filtration with a silent pump and integrated heater.

JUWEL Rio aquariums feature the MultiLux LED lighting system, designed to support plant growth and enhance fish coloration. The lighting differs based on model size. The Rio 125 includes LED 80, the Rio 180 uses LED 100, the Rio 240 and 290 include LED 120, and the Rio 350 and 450 are equipped with LED 150 units. Each system includes two LED tubes for balanced, energy-efficient illumination.

Yes, the JUWEL Rio range can be adapted for saltwater and reef aquariums with the right equipment. While the standard configuration is ideal for freshwater environments, marine conversions are common. These often involve removing the internal filter in favour of a sump or external filter, installing a protein skimmer, and upgrading the lighting system to suit coral growth.

JUWEL offers the Rio range in four contemporary colours to suit a wide variety of home styles. These include a classic black, a bright modern white, a light wood finish reminiscent of oak, and a rich dark wood for a more traditional look. All colour options are matched across tanks and cabinets for a coordinated appearance.

JUWEL Rio aquariums are available on their own or with a matching cabinet. The cabinets are custom-built for each Rio model, providing excellent support and ample storage for aquarium accessories. At Charterhouse Aquatics, you can purchase the aquarium and cabinet together as a value bundle or individually depending on your needs.
