The UNS 90SA Dual AIO is a 47.9-gallon shallow rimless aquarium constructed from 8mm ultra-clear glass with an integrated quadruple-chamber rear filtration system. Combining an expansive horizontal footprint with a low height, this shallow design provides a unique stage for emergent hardscape, shallow reef layouts, and pond-style aquascapes. By concealing equipment behind a sleek black acrylic wall, the 90SA eliminates external hoses and canisters, delivering a clean, plug-and-play display.
