How Thick Does Acrylic Need To Be For An Aquarium?

Introduction

Acrylic is a popular material for aquariums because it is clearer than glass and is less likely to break. However, the thickness of the acrylic needed for an aquarium depends on a few factors.

Factors that Affect the Thickness of Acrylic Needed for an Aquarium

The Size of the Aquarium

The larger the aquarium, the thicker the acrylic will need to be to prevent it from bowing or cracking under the weight of the water. The thickness of the acrylic needed will also depend on the shape of the aquarium and the type of reinforcement that is used.

The Depth of the Water

The deeper the water in the aquarium, the more pressure it will put on the sides and bottom of the tank. This will require thicker acrylic to avoid bowing or cracking.

The Type of Fish and Decorations

If the aquarium will house large fish or heavy decorations, the acrylic will need to be thicker to avoid cracking or breaking.

Calculating the Thickness of Acrylic Needed for an Aquarium

To calculate the thickness of acrylic needed for an aquarium, you will need to consult a chart that provides the appropriate thickness based on the size of the aquarium and the depth of the water. These charts are readily available online or from a supplier of aquarium materials.

When calculating the appropriate thickness of acrylic, it is important to not only consider the size of the aquarium but also the amount of water it will hold. A larger aquarium with a lower depth of water may not require as thick of acrylic as a smaller aquarium with a greater depth of water.

Reinforcing Acrylic

Reinforcing acrylic can help to further support the material and prevent cracking or bowing. The most common method of reinforcing acrylic is with fiberglass, which is applied to the surface of the acrylic.

To apply fiberglass to acrylic, the surface of the acrylic must be cleaned and sanded. A layer of resin is then applied to the surface of the acrylic, followed by a layer of fiberglass. Additional layers of resin and fiberglass can be applied until the desired thickness is achieved.

While reinforcing acrylic can help to make it stronger, it is important to remember that it will not make it unbreakable. Careful handling and regular maintenance are still important to ensure the longevity of the aquarium.

Conclusion

When building an aquarium with acrylic, it is important to consider the size and shape of the aquarium, the depth of water, and the type of fish or decorations that will be included. By using a chart to calculate the appropriate thickness of acrylic and considering reinforcement options, you can create a strong and durable aquarium that will provide a beautiful display for years to come.
