How To Choose The Right Aquarium Heater

If you have the aquarium, make sure to keep a suitable temperature for the health of your fish. What happens if you are unable to keep a steady or warm enough temperature in the tank? For some special delicate underwater life, it could cause stress. To prevent stress and any other issues that come with an unstable aquarium temperature, here are a handful of tips to help you in deciding on the right heater for your aquarium.

First, figure out the size of your aquarium. A larger tank will need higher wattage to produce more heat. The general guideline is that you need 5 watts per gallon to heat single gallon of water. So a 20-gallon aquarium would call for a 100 watt water heater. The five watts per gallon guideline is not fixed, particularly with large tanks and with homes that are centrally heated. Also, bigger tanks lose heat more slowly than smaller tanks. If you had a 30 or 40-gallon aquarium, you’ll see a 100-watt heater will be enough.

When you have established the temperature your fish lives best in, compare it to the room temperature, where the fish tank is located. Find the distinction between the two temperatures: a 9 degrees Fahrenheit and lower difference needs just a low-watt heater, or when there is a distinction of more than 25 degrees F, a higher-watt heater is recommended. To measure the temperatures more accurately, position one thermometer inside the tank and one outside.

There are two types of heaters for tanks, an immersible heater is placed above the aquarium’s water line, however the submersible heater is positioned entirely underwater. The latter method is more preferred, because it can adjust the water temperature more evenly.

There are actually even more sorts of heaters to choose from, but typically most tank owners use the standard combined heater/thermostat units, which are inexpensive and quite accurate. These other types are, separate thermostat heater, undertank heater, heating cable, in-line heater and thermo-filter.

Also, it is important to monitor the temperature in your aquarium with a thermometer.
