Description

AquarCraft low-iron glass reduces the green tint found in standard aquarium glass, revealing fish, plants, and hardscape in clearer, more natural color. The rimless design keeps every view clean and unobstructed. From 91% light-transmitting low-iron glass to precisely bonded rimless corners and safety-chamfered edges, every detail is designed for a cleaner view and smoother handling. Standard aquarium glass carries a visible green tint that dulls plant colors and fish patterns across a large viewing pane. AquarCraft tanks use low-iron, ultra-clear glass with a 91% light transmission rate, so the water column reads true from every angle — the same clarity hobbyists look for in showcase planted-tank builds, now standard on every AquarCraft size. AquarCraft’s rimless edges are fused with a German-engineered structural grade glass adhesive instead of a plastic frame, eliminating the visible seam line that runs along conventional tank edges. The result is a gallery-clean silhouette and a bonded structure built for long-term stability at 6mm and 8mm glass thickness. Every corner is then safety-chamfered — smoothed and rounded rather than left as a sharp cut edge — for safer handling during setup, aquascaping, and routine maintenance. A rimless aquarium brings natural color and a peaceful underwater view to your workspace. The open rimless design keeps planting, trimming, and routine maintenance within easy reach. The clean rimless design showcases fish and aquascaping while blending into modern interiors.

such a clean design you don't find often; long across but super thin tank. it is great value for the money considering the high quality thick glass material. the lighting makes the ultra clear glass really pop, and the versatility of the long shape is perfect for a unique touch.

  • Size not as advertised, only about 3 gallons when it is supposed to be 4 Size not as advertised, only about 3 gallons when it is supposed to be 4
Size: Nano Color: 3.5 Gallons
I knew soon as I opened and compared to my 5 gallon tank that this was not 4 gallons. Measured all sides which came out to be slightly over 1 cm less than advertised on 2/3 sides and 2.5 cm less on the last side. When I calculated the volume using my exact measurements It came out to 3.25 gallons. This was also calculated using the width of the class in my measurements as it was shown in the measurements provided in the photo, so the actual volume of water it can hold is even less and is closer to about 3 gallons total. 1 gallon less may not seem like a ton but when when the tank is only a few gallons, it makes a huge difference. I am extremely disappointed ad this is too small for what I was intending to use it for. I decided I’d make the small size work for a shrimp tank instead but it also started leaking water in less than 24 hours. Overall I do not recommend this tank at all ... show more

  • Great for a terrarium Great for a terrarium
Size: Nano Color: 3.5 Gallons
I found water maintenance too hard for a tiny aquarium like this, especially if you plan on having living creatures in it. But it works amazing for terrariums. The size makes it easy to place on a shelf. It gave me a new hobby I am obsessed with. So, five stars.
