Buying Guide: Key Purchase Considerations
- Overflow design: Center vs. peninsula vs. side overflow affects plumbing layout, visible bulkheads, and maintenance access. Choose based on preferred cabinet and display orientation.
- Glass and build: Starfire glass improves clarity and color rendering; thicker panels (12mm) generally offer better structural integrity for large systems.
- Sump integration: Look for built-in sumps or compatible sump configurations with refugium, skimmer, and filtration sock spaces. Confirm included fittings and ease of access for maintenance.
- Cabinet and stand: Ensure the cabinet can support the weight of full water volume, equipment, and rock; verify access for cable management and external gear.
- Dimensions and room fit: Check footprint, height, and door clearance. Measure doorways and stand stability to avoid setup challenges.
- Water flow and filtration: Consider the number of returns, pump compatibility, and planned coral load. Balanced flow reduces dead zones and helps corals thrive.
- Electrical needs: Integrated stands with power outlets help manage equipment clutter; account for surge protection and cable management.
- Maintenance practicality: Look for accessible filtration chambers, easy-sump access, and a design that minimizes algae buildup and leaks.
