Our regular 30C listing remains available year-round. A Perfect Cube. A Composition You Can Walk Around. Most aquariums have a front. The 30C doesn't — three equal 11.8" sides make it a square canvas that reads beautifully from every angle. It's the natural home for a single dramatic stone, a bonsai-style tree, or a moss mountain: compositions built in the round, not against a back wall. Low-iron, ultra-white glass on every face keeps the view true wherever you stand. Why You'll Love It True cube proportions — 30 × 30 × 30 cm invites centered, sculptural layouts you can view from any side. Low-iron, ultra-white glass — over 91% light transmittance, so your scape shows its true colors instead of a green tint. Hand-finished edges — mirror-polished and chamfered, so every edge is smooth to the touch and safe to work around. Clean silicone seams — hand-applied German silicone in thin, even lines that almost disappear once the tank is filled. The Cube Canvas Equal width, depth, and height change how you compose. Instead of foreground-to-background perspective, a cube rewards a strong centerpiece — one stone, one branch, one island — with open water around it. Place it on a counter or room divider and it becomes a piece you circle, not just a screen you face. Crystal Clear Glass Standard aquarium glass carries a green cast that hides the very colors you scape for. Every 5mm panel here is low-iron, ultra-white glass with over 91% light transmittance — acid and alkali resistant, and clear enough that reds stay red and greens stay green. Hand-Finished Craftsmanship Every edge is mirror-ground and chamfered by hand, and every seam is laid in fine German silicone by experienced craftsmen. On a tank meant to be seen from all sides, that finish is the difference.
