Cylinder Aquaria made of Acrylic

A cylinder is the ultimate shape for 360-degree viewing. This type of tank will let you admire the marinescape from all sides equally. Hydrosight is your first stop when you are looking for cylinder aquariums and round fishtanks.

It can be anything from waist height to full room height. We are able to fabricate up to 2,0 meters height (assuming base and lid = room height). It is a specialty of cylindrical tanks, that they can be relatively high, lightweight and affordable at the same time. A cylinder can bear water loads much better than a comparable rectangular tank.

Acrylic tubes of standard outside diameters (300, 457 and 600mm) are fabricated in a centrifugal casting process and can be made in large quantities on demand. Cylinders of larger diameter are manually made. The production process limits the maximum diameter to 2,2m for the acrylic cylinder.

The window is made of the finest thermoformed acrylic with the minimum amount of seams - usually one. And even this bond is virtually invisible - you will have to search for it, to be able to notice. Each tanks window thickness is individually adapted to the water pressure for maximum safety.

North American buyers: please note that we only deliver outside Europe in larger quantities.
