Buying Guide: Key Purchase Considerations
- Room and Stand Compatibility: A 100 gallon tall aquarium is heavy. Verify cabinet support, floor strength, and doorway clearance before purchase.
- Filtration Needs: Consider whether you prefer an integrated sump or external canister filtration. Sumps offer expandable media; canisters provide modular upgrades.
- Glass Type and Clarity: Low-iron glass improves viewing clarity. Tempered glass adds safety for large displays but may limit customization options in some models.
- Lighting and Aesthetics: Built-in LED systems simplify setup but assess light spectrum for your intended fish or corals. Ensure cabinet hardware complements your space.
- Saltwater vs Freshwater: Saltwater setups may require reef-ready features, stronger filtration, and space for protein skimmers and reactors. Freshwater systems often prioritize plant and community compatibility.
- Maintenance Access: Look for accessible cabinet doors, cable management, and easy media replacement to reduce maintenance time.
