Current product; shares the exact tank body of the original MAX Nano (2016) and the discontinued ReefLED-50 refresh, so this record covers both. 45cm cube = 17.7 in, 8mm ultra-clear glass; 75L/20gal total, 62L/16.5gal display, ~13L/3.5gal rear sump. Integrated Nano XL skimmer, ReefATO+- and NanoMat-ready sump, 225-micron sock. Return pump Sicce ~950 L/h (= 250 gph). The 132cm/54in figure is total height with cabinet, not tank height. Red Sea publishes no internal rear-chamber dimensions, so chamber dims left null. SKU 254020 = tank only.
