My Buying Guide on ’20 Gallon Acrylic Aquarium’
As an experienced aquarium enthusiast, I have owned various types of tanks over the years. I have found that a 20 gallon acrylic aquarium is the perfect size for those looking to start or expand their collection. It offers a decent amount of space for a variety of fish and is also easy to maintain. In this buying guide, I will share my knowledge and tips on purchasing a 20 gallon acrylic aquarium.
Size and Shape
The first thing to consider when purchasing an aquarium is its size and shape. A 20 gallon tank is spacious enough to house different types of fish, but not too large that it becomes difficult to maintain. When it comes to shape, acrylic tanks offer more options compared to glass tanks as they can be molded into different shapes with smooth curves. This not only adds aesthetic appeal but also provides more swimming space for your fish.
Material
Acrylic is a popular material used for aquariums due to its durability and clarity. Unlike glass, acrylic tanks are less prone to cracking or shattering and are also lighter in weight. This makes them easier to move around and less likely to cause damage if accidentally dropped. Additionally, the clarity of acrylic allows for better viewing of your fish, making it a great choice for showcasing your aquatic pets.
Accessories
When purchasing a 20 gallon acrylic aquarium, make sure it comes with all the necessary accessories such as a filter, heater, lighting, and thermometer. These are essential items that will help maintain the water quality and temperature in the tank, ensuring the health of your fish. It is also important to check if these accessories are specifically designed for use with acrylic tanks as some may be made for glass tanks only.
Price
The price of an acrylic tank may be slightly higher compared to glass tanks due to its material and additional features such as curved shapes. However, considering its durability and versatility, investing in an acrylic tank is worth it in the long run. It is important to do some research on different brands and compare prices before making a purchase.
Maintenance
One advantage of using an acrylic tank is that they are easier to clean compared to glass tanks. Acrylic does not scratch easily so you can use algae scrapers without worrying about damaging the surface. However, it is important not to use abrasive materials as they can cause scratches on the tank walls.
Conclusion
In conclusion, a 20 gallon acrylic aquarium is a great option for both beginners and experienced hobbyists alike. Its size allows for a variety of fish while still being manageable in terms of maintenance. When purchasing one, consider factors such as size and shape, material, accessories included, price point, and maintenance requirements. With proper care and upkeep, your 20 gallon acrylic aquarium will provide endless enjoyment for you and your aquatic pets.
