Aquarium Volume Calculator

Calculation Tips

• Actual water volume is approximately 90% of tank size (accounting for substrate and decorations)
• Saltwater is about 2.5% heavier than freshwater (specific gravity 1.025)
• Heater guideline: approximately 2W per liter (for heating from 15°C to 26°C)
• Recommended filter flow rate: 5-10x tank volume per hour
• Ensure your tank stand can support the total weight of water, tank, and equipment
