Oase · Rimless
A rimless, mitre-cut Optiwhite tank built for aquascaping, sold as a set with a flush matching cabinet. The cabinet is laid out for a scaper, with a pull-out shelf for an external filter, magnetic tool holders and a hidden cable port. No light or filter is included, so you build the tech around it yourself.
Updated
Aquascapers who want an open-top, show-quality tank and cabinet that match, and already know which light and filter they want.
Open-top tanks lose more water to evaporation and need a light that hangs or mounts on the rim.
