Description
The UNS R240 Reef System is the largest aquarium in the UNS lineup. This model sets itself apart from the standard reef series with a euro-braced top for enhanced structural security, dual overflows, and a reinforced stand. It retains UNS’s signature craftsmanship, including 45° mitered edges, black silicone, and a double-pane glass bottom. The aluminum-framed stand features double support bars on the back and additional horizontal reinforcement for superior stability. Its magnetic, fully removable doors provide effortless access for routine maintenance. The R240 also includes an expanded electrical box with increased space for dosing containers and controllers.
The R240’s stand does not come with leveling feet. The stand will need to be leveled with shims before filling.
