The biOrb HALO 15 MCR aquarium has a chic and minimalist design that adds joy and wonder to your home. This 4-gallon (15 L) acrylic aquarium has a unique layered design with a gray lid and base, giving it a stylish appearance. Its compact size (12 x 12 x 13 in.) is ideal for desktop or tabletop display. The hidden water line and 360-degree view create the illusion of a floating underwater world in your room. The aquarium comes with everything you need to start your new hobby, including an acrylic tank, low-voltage air pump, LED multi-color remote-controlled (MCR) lighting, filtration, and instructions. Made from acrylic, the aquarium is 10 times stronger and 23% clearer than glass, and it also acts as a good insulator to retain heat. The MCR light allows you to choose from 16 preset colors and control the brightness, enhancing your sense of well-being. The 5-step filtration system ensures clear and healthy water by providing biological, mechanical, and chemical filtration, as well as water stabilization and oxygenation. The filter is conveniently located at the bottom of the aquarium, and the ceramic media surrounding it promotes the growth of beneficial bacteria. Setting up and maintaining the biOrb aquarium is quick and easy, allowing you to unleash your creativity and decorate it with a variety of biOrb aquarium decorations. Depending on the fish species you choose, maintenance may only require around 15 minutes per month using a biOrb Service Kit. The aquarium is backed by a 2-year warranty, allowing you to enjoy the wonders of nature in your home with biOrb.
