My Buying Guide on ’20 Gallon Acrylic Aquarium’

As an experienced aquarium hobbyist, I understand the importance of choosing the right aquarium for your beloved aquatic pets. After extensive research and personal experience, I have compiled a buying guide for a 20 gallon acrylic aquarium that will help you make an informed decision.

What is an Acrylic Aquarium?

An acrylic aquarium is made of clear plastic sheets that are molded to form a tank. They are lightweight, strong, and have better clarity compared to glass tanks. They also come in a variety of shapes and sizes, making them a popular choice among aquarium enthusiasts.

Size and Shape

The first thing to consider when buying an acrylic aquarium is its size and shape. A 20 gallon tank is considered ideal for beginners as it provides enough space for a variety of fish species. However, you must also consider the dimensions of the tank to make sure it fits in your desired location.

Moreover, acrylic tanks come in various shapes such as rectangular, hexagonal, and bow-front. Each shape has its own pros and cons, so choose one that best suits your preference and the type of fish you plan to keep.

Material Quality

The quality of the material used to make the tank plays a crucial role in its durability. Acrylic tanks are known for being strong but can be prone to scratches if not handled carefully. Make sure to check if the tank has any scratches or imperfections before purchasing.

Additionally, opt for high-grade acrylic tanks that are at least 8mm thick to ensure sturdiness and prevent any potential leaks or cracks in the future.

Filtration System

A good filtration system is essential for maintaining a healthy aquatic environment. When buying an acrylic tank, make sure it comes with a built-in filtration system or at least has enough space for you to install one. Canister filters or hang-on-back filters are ideal choices for acrylic tanks.

Lighting

The lighting system in your aquarium not only enhances the visual appeal but also plays a vital role in plant growth and fish health. Acrylic tanks usually come with LED lighting systems that provide ample light and consume less energy compared to traditional fluorescent lights.

Additional Features

Sometimes, additional features can make your aquarium stand out even more. Look out for tanks that come with accessories such as decorative backgrounds, gravel or substrate, or even starter kits that include water conditioners and food samples.


In conclusion,

A 20 gallon acrylic aquarium is a great choice for beginners due to its convenient size and durability. When buying one, consider factors such as size and shape, material quality, filtration system, lighting, and additional features. By following this guide, you can ensure that you choose the perfect 20 gallon acrylic aquarium that will provide a suitable home for your aquatic pets.
