Introduction to Aquarium Materials

 

Selecting the right material for an aquarium is critical for durability, safety, and aesthetics. This guide explores common options, their pros/cons, and ideal use cases.

1. Glass Aquariums

a. Ultra-Clear Glass (Low-Iron Glass)

  • Pros: 92+% light transmission, minimal green tint, scratch-resistant.
  • Cons: Expensive; requires careful handling.
  • Best for: Reef tanks, planted aquariums.

b. Tempered Glass

  • Pros: 5x stronger than regular glass; shatters safely into granules.
  • Cons: Cannot be drilled post-production.
  • Best for: Large tanks (>50 gallons).

c. Standard Float Glass

  • Pros: Affordable; widely available.
  • Cons: Visible green hue; lower clarity.

2. Acrylic (PMMA) Aquariums

  • Pros: Lightweight (50% lighter than glass), impact-resistant, customizable shapes.
  • Cons: Prone to scratches; yellows over time without UV inhibitors.
  • Best for: Custom designs, temporary displays.

3. Other Materials

a. Polycarbonate

  • High impact resistance but poor scratch tolerance.

b. Concrete/Epoxy (DIY Tanks)
