007 – Tank Construction

Tanks are sold in many shapes and sizes, but they are only made of two types of material: glass and acrylic. Here are some advantages and disadvantages of the two types:

Glass

Acrylic

cheap

expensive

breaks easily

scratches easily

high refraction

low refraction (distorts less at angle)

heavy

light

tank support at edges

entire base needs support

easier to clean

abrasives causes scratches

Perspex is used occasionally in place of acrylic. Most of the comments that apply to Acrylic apply to Perspex.

Glass aquariums are held together either with a metal frame or a special super-strong adhesive.

Aquariums are sometimes found that are molded entirely of one piece of glass. These aquariums often have unsightly bubbles in the sides of the tank. They shatter relatively easily. They tend to distort the view of the fish at certain angles.
