Buying Guide
- Space and footprint: Corner models maximize room corner usage; measure available space before choosing.

- Filtration: All-in-one kits with integrated filters simplify setup; upgrade options help with heavier bioloads.
- Lighting: LED lighting enhances plant growth and fish color; ensure the light is adjustable for day/night cycles.
- Maintenance: Self-cleaning features reduce routine tasks; consider how you’ll perform water changes and monitor water quality.
- Upgradability: If you plan to move to a larger tank, choose kits compatible with standard filter cartridges and replacement parts.
