Buying Guide: Key Purchase Considerations
- Tank type: Rimless tanks provide a modern look and wide viewing angles but require careful handling. Consider a lid or cover for jumpers or evaporative losses.
- Glass quality: Low iron glass improves clarity and color; look for thickness (at least 6mm) for durability in 15-gallon models.
- Filtration: Choose a system sized for 15 gallons with adjustable flow to avoid stressing small fish. Submersible filters can save space but check noise levels.
- Heating: For tropical setups, select a heater with a wattage appropriate for 15- to 25-gallon tanks and automatic temperature regulation to maintain stable conditions.
- Lighting: App-controlled or programmable lighting helps with plant or coral growth (if reefing) and enhances color display. Ensure compatibility with your chosen inhabitants.
- Complete vs. upgrade: Complete starter kits reduce missing parts but verify that included equipment fits your plan for future upgrades (corals, livestock, substrate, and decor).
- Maintenance: Look for easy access to filter media, a reliable pump, and a simple setup guide to cycling the tank safely before introducing fish.
