Differences Between Glass and Acrylic Aquariums

There are differences between glass and acrylic, and thus between glass and acrylic aquariums.

Scratch Resistance, Repair and Weight

Some of the differences include that glass is scratch resistant while acrylic can scratch more easily. But the scratches on acrylic can be removed and polished away easier than on glass. Scratches on glass tend to be permanently visible.

Acrylic aquariums are not as heavy as glass aquariums and can be moved easier than glass tanks if you need to move your aquarium. Acrylic roughly weighs half the weight of glass.

Shapes

One of the great drawbacks of glass aquariums is that the shape of glass aquariums are limited. Acrylic tanks offer a variety of shapes. You get bowl form, hexagon and rectangular shapes, and cubes, to mention a few.

Strength

The impact resistance of an acrylic aquarium is much higher than that of a glass tank. The acrylic aquarium will not break as easily as a glass tank when your child or pet accidentally bumped into it. Acrylic is 17 times stronger than glass.

As acrylic is so strong, it is often used for aquariums without rims. Especially the smaller fish tanks nowadays come without rims as you need as much surface as possible to make all the fish and trimmings in your fish tank visible.

Clear vision

Acrylic tanks are also clearer than glass fish tanks.  You can also use acrylic fish tanks for salt and freshwater fish.

GloFish

Acrylic aquariums are also popular with GloFish enthusiasts. Because they can be rimless it shows off all the colors of your GloFish from all angles.

FAQs

How long do acrylic fish tanks last?

The short answer is anything from 5 to 15 years. Acrylic tanks don’t last as long as glass aquariums.

However, this is not necessarily true. If the structure is sound and you maintain your acrylic tank well, you should be able to get up to 15 years of use from one.

As with glass aquariums, you will not get long service from your acrylic tank if you don’t maintain it effectively. Treasure your aquarium and you will get many years of joy from your acrylic tank.

Can acrylic tanks leak?

You will experience fewer cracks, chips or leaks with your acrylic tank than with a glass aquarium. Acrylic aquariums are often advertised as leak-resistant, because if a leak does occur, it can easily be fixed.

There are excellent acrylic glues on the market for you to use. You can repair the small leaks yourself.

Do acrylic tanks crack?

Unlike glass tanks, acrylic versions are less prone to breaking or cracking. And an important feature is that an acrylic tank doesn’t require resealing as they get older.

If an acrylic tank is put together correctly, it may crack on the sheeting itself. But this will happen before a seam comes apart. So, they can develop cracks on the surface over time but will not crack on the seams to cause leaks.

Conclusion

The trend with aquatics hobbyists is to change to acrylic tanks. Acrylic aquariums are becoming very popular and you can’t go wrong with any of the options we have discussed.
