Despite the G2 label, the Nano XL is the first Red Sea tank with 20”x20”x24” dimensions (50x50x60cm) giving it a working volume of 125 liters, or 33 gallons capacity. The tank is constructed from solid 10mm thick low iron glass and can sit on a redesigned G2 cabinet, available in either black or white. The inbuilt Sicce return pump produces 1550lph/ 409gph, so it circulates the tank volume up to 12 times per hour. With the addition of a heater (not included,) it really is plug-and-play, and Max Nano remains the most featured loaded and complete nano reef tank available on the market today.
