🐠 Fish Tank Size Calculator
📏 fish tank size calculator — worldwide standard: calculate exact volume (US gal, UK gal, liters), heater wattage, filter flow, substrate weight, and safe fish stocking. Used by aquarists from USA, Europe, Asia & beyond. Advanced real-time graph tracks volume vs. bioload capacity (Neon Tetra equivalent). Follows both metric & imperial guidelines.
📐 Unit system:
⚡ Advanced: Auto-updates tank volume, weight & bio-capacity.
🌍 Global standards (US, UK, Metric)
💡 Info per factor (USA & worldwide):
• Heater: 2.5–5 watts per US gallon (room temp difference ~8-10°F).
• Filtration: 4-6x tank volume turnover per hour.
• Stocking: 1 inch per US gallon or 1 cm per liter for small fish (Neon Tetra reference).
• Substrate: Avg. gravel density 1.5 kg/L (~12.5 lbs per US gal of substrate volume).
• All values automatically in both imperial & metric.
