Acrylic vs Glass Aquarium – Which one is better?

Choosing the right material for your aquarium is a crucial decision that impacts both looks of your aquarium and it’s function. Acrylic and glass are the two most popular options, each with unique features and benefits. In this article, we will talk about choosing Acrylic vs Glass Aquarium.

When choosing between acrylic and glass for your aquarium, it’s essential to consider the type of aquatic environment you wish to create. For instance, if you’re planning to houseĀ saltwater aquarium fish, acrylic might be a more suitable option due to its light weight.

Acrylic vs Glass Aquarium – Comparison Table

Material Composition

Acrylic: A Brief Overview

Acrylic is a type of plastic known for its transparency and strength. It’s made from polymerized methyl methacrylate, resulting in a lightweight and versatile material.

Glass: A Brief Overview

Glass is made primarily of silica and has been a staple in aquarium construction for decades. It’s robust and non-reactive, making it a reliable option for aquatic environments.

Weight Considerations

Acrylic: Lightweight Marvel

Acrylic aquariums are much lighter than glass ones, making them easier to move, especially for larger tanks.

Glass: Heavier Yet Sturdy

Glass aquariums are heavier, but this weight adds to their stability and sturdiness, helping to prevent accidental tipping.

Clarity and Aesthetics

Acrylic: Crystal Clear Views

Acrylic offers exceptional clarity, providing unobstructed views of the aquatic life inside.

Glass: Traditional Beauty

Glass provides a classic look with its natural shine and clarity, though slightly less clear than acrylic.

Strength and Durability

Acrylic: High Impact Resistance

Acrylic is highly impact-resistant, making it less likely to crack or shatter.

Glass: Scratch and Shatter Resistance

While glass can shatter upon impact, it is more scratch-resistant, keeping it clear and unblemished longer.

Maintenance and Cleaning

Acrylic: Ease of Maintenance

Acrylic aquariums are easy to maintain but care must be taken to avoid scratches during cleaning.

Glass: Cleaning Challenges

Glass aquariums can be harder to clean due to their weight and susceptibility to watermarks and algae buildup.

Customization and Design Flexibility

Acrylic: Versatility in Shapes

Acrylic’s flexibility allows for a wide range of shapes and sizes, catering to specific aesthetic preferences.

Glass: Limitations in Design

Glass is usually limited to standard rectangular or square shapes due to its rigidity.

Cost and Affordability

Acrylic: Initial Investment

Acrylic aquariums generally cost more upfront due to their premium quality and complex manufacturing process.

Glass: Long-term Value

Glass aquariums are more affordable initially and offer long-term value due to their durability.

Temperature and Chemical Resistance

Acrylic: Sensitivity to Chemicals

Acrylic can be sensitive to certain chemicals, which may cause clouding or damage.

Glass: Superior Resistance

Glass is more resistant to temperature changes and chemical exposure.

Seam and Joint Integrity

Acrylic: Seamless Appearance

Acrylic often features seamless joints, creating a smooth appearance and reducing the risk of leaks.

Glass: Visible Seams

Glass aquariums typically have visible seams where the panels are joined with silicone.

Longevity and Wear

Acrylic: Potential Yellowing Over Time

Acrylic can yellow over time, especially when exposed to UV light.

Glass: Long-lasting Clarity

Glass maintains its clarity over time with minimal risk of discoloration.

Impact on Aquatic Life

Acrylic: Beneficial Properties

Acrylic’s insulation helps maintain stable water temperatures, benefiting aquatic life.

Glass: Safe Environment

Glass provides a safe, inert environment for aquatic life, with no risk of chemical leaching.

Transport and Installation

Acrylic: Ease of Handling

Acrylic is easier to transport and install due to its lightweight nature.

Glass: Precautions During Transport

Glass requires careful handling during transport due to its weight and fragility.

Environmental Considerations

Acrylic: Environmental Impact

Acrylic production involves petroleum-based materials and has limited recycling options.

Glass: Eco-friendly Aspects

Glass is made from natural materials and is fully recyclable, making it more eco-friendly.

Repair and Replacement

Acrylic: Repair Feasibility

Acrylic can be repaired easily with specialized kits, extending its lifespan.

Glass: Replacement Needs

Glass is harder to repair, often requiring complete replacement if damaged.


Both acrylic and glass aquariums offer unique advantages. The choice depends on your preferences, budget, and specific needs. Understanding the differences helps you make an informed decision for your aquatic setup.
