Buying Guide: Key Purchase Considerations
- Tank type compatibility: Saltwater vs freshwater systems may require different stone materials and sizes. Look for statements about saltwater suitability when applicable.
- Bubble size and oxygenation: Fine, uniform bubbles improve gas exchange and help maintain healthy dissolved oxygen levels. Lime wood often yields finer bubbles than some plastics.
- Mounting and position: Consider whether a clip, base, or suction cups are included. Secure installations reduce noise and movement in the tank.
- Maintenance and durability: Wooden and natural materials require gentle handling; ensure the product notes indicate durability and ease of cleaning.
- System size and pump requirements: Some products require an external air pump not included in the package. Plan for compatible accessories.
