수조 용량과 목표 수온을 입력하면 필요한 히터 와트수를 계산합니다. 온도 차이 기반 정확한 히터 용량 추천.
A general rule is 5 watts per gallon for a 10°F temperature increase. For example, a 50-gallon tank needs 250 watts to raise temperature 10°F. Larger tanks and colder rooms may need more wattage.
Most tropical fish prefer 75-80°F (24-27°C). Coldwater fish prefer 65-72°F (18-22°C). Specific species have different requirements, so research your fish's needs. Use a reliable thermometer to monitor temperature.
This calculator uses standard formulas for heater sizing. Actual needs depend on room temperature, tank insulation, and heater efficiency. For precise sizing, consult an aquarium specialist.
For tanks under 50 gallons, one heater is usually sufficient. For larger tanks, two smaller heaters provide redundancy and better temperature distribution. If one fails, the other maintains temperature.
Use a reliable thermometer to monitor temperature daily. Adjust the heater dial gradually. Most heaters have a thermostat that maintains set temperature. Check heater function regularly and replace if it fails.
