EXT Shallow

The external overflow tank is a popular tank choice in the reef keeping hobby in recent years because of its highly customizable options in its filtration setup and its opportunity in maximizing space for aquascaping. Fiji Cube launches a series of ultra-clear low iron glass aquariums with Fiji Cube’s low-profile external overflow design. The attractiveness and uniqueness of the Fiji Cube external overflow glass aquarium tanks stand out with its slim overflow design and extra thick glass selection, achieving the best in class tanks in both design and quality. The simple plug and play design of the overflow box only makes the set up easier and better. All Fiji Cube tanks are built with ultra-clear low iron glass.

All Fiji Cube EXT aquarium tanks come with the appropriate size of external overflow and return nozzle kit. The overflow box is made of full cast acrylic and features a low profile design. For smaller EXT tank packages, the “Herbie” overflow design features efficient and quiet flow, as well as an emergency drain for added safety. Incorporating animal bean style overflow is possible with Fiji Cube’s overflow boxes. For larger EXT tank packages, “Bean Animal” overflow design can be a plumbing option.
