Not all aquarium walls should be cleaned the same way.
Did You Know?
Not all aquarium walls should be cleaned the same way.
Glass is harder and more scratch-resistant, so a dedicated algae scraper or razor-style blade can be useful for stubborn algae, including coralline algae in saltwater tanks. Keep the blade at a shallow angle, rinse it often, and use gentle, straight strokes.
Acrylic is much softer than glass, so metal blades, rough pads, and household scrubbers can leave permanent scratches. For acrylic tanks, use only a soft pad, plastic scraper, or cleaning tool labeled acrylic-safe.
The biggest scratch risk for both materials is sand or gravel trapped under a magnetic cleaner or pad. Inspect your tools first, and stop short of the substrate line rather than dragging grit across the viewing panel.
Match the tool to the tank:
- Glass: Aquarium-safe pad, magnetic cleaner, or careful razor scraper
- Acrylic: Soft acrylic-safe pad or plastic blade only
- Never: Use household cleaners, soaps, or abrasive kitchen pads inside an aquarium
A clear tank starts with the right tool—not more pressure.
