🐠 Aquarium Volume Calculator
🌊 Professional aquarium volume calculator — instantly compute total water volume, net displacement, heater power, filter flow, and fish stocking limits.
Supports rectangular & cylindrical tanks, metric/imperial units, substrate & decor displacement.
Accurate for hobbyists worldwide (liters, US gallons, Imperial gallons). Includes US-based guidelines for equipment sizing.
Displaces water volume from bottom area

💡 Advanced displacement: Substrate volume (base area × height) + decoration % = realistic water volume.
📊 VOLUME SUMMARY (Worldwide)
Gross Volume: 0 L | 0 US gal | 0 Imp gal
💧 Net Water Volume (after displacement):
0 L · 0 US gal · 0 Imp gal
0 L · 0 US gal · 0 Imp gal
⚙️ USA STANDARD EQUIPMENT & GUIDELINES
🔥 Heater power (USA rule: 5 watts/US gal net) → 0 W (recommended)
🌀 Filter flow rate (6-10x turnover) → 0 – 0 US gal/hour | 0 – 0 L/h
🐟 Fish stocking (1 inch per US gallon – conservative) → max ~0 inches of small fish (0 cm)
⚖️ Water weight (full net volume): 0 lbs | 0 kg
🌐 GLOBAL FACTORS & NOTES
📏 Volume in liters → US gal ×0.26417 | Imp gal ×0.21997
🧪 CO₂ / light reference: For planted tanks > 100 L (27 gal) moderate light + CO₂ recommended.
🧊 Temperature stability: each 10°F (5.5°C) change = adjust heater size. Use controller.
✔ Based on American Aquarium standards (heater 5W/gal, filter turnover 6-10x, 1 inch per gal). Adapt for marine, cichlids, or heavy bioload.
📈 Volume Comparison Graph (Net Water Volume vs Standard Tank Sizes)
*Bar chart compares your net water volume (US gallons) with typical reference aquariums (10, 20, 29, 55, 75 US gal). Helps to visualize tank size category.
