Buying Guide
What should you consider when choosing a 5-gallon glass tank?
- Filtration: Do you prefer a built-in filter or plan to add external filtration? Stronger filtration supports more occupants or cleaning-heavy setups.
- Lighting: Integrated LED lighting helps plant growth and enhances viewing. Consider color options and timing settings.
- Glass type: Low-iron glass reduces green tint and provides truer color viewing. Check for edge polishing to avoid cuts during setup.
- Lid and cover: A lid reduces evaporation and keeps curious pets away. Ensure compatibility with your filter and light.
- Accessories: Heaters, substrates, and decor vary by kit. Choose a kit that includes or is compatible with your intended fish and plants.
- Placement: Consider space, surface stability, and room temperature. Small tanks still require stable environments for water quality.
