Tips for choosing an best aquarium heater for Small & Large Tanks

When it comes to aquarium fish, there are hundreds of species to choose from. However, for the most part, aquarium enthusiasts tend to prefer tropical aquarium fish to cold-water species. Tropical fish can be found all over the world in all types of aquatic ecosystems and each species has its own unique requirements when it comes to tank parameters.

While water quality tops the list of important tank parameters, water temperature is also important.

Not only do you have to heat your tank to the correct temperature, you also have to maintain that temperature. Aquarium fish can easily be stressed by changing the conditions in your tank, which includes the temperature of the tank.

But how do aquarium heaters work and what are the different types? Read on to find out.

 

Where to place the aquarium heater?

This is often a simple but overlooked question when it comes to aquarium heaters. It is recommended to keep the new heater running with the water flow. It could be the input or the output of the filter or even the current coming from a power head.

But why?

This is because the water that flows directly past the aquarium heater facilitates heat diffusion throughout the aquarium.

 

How much electricity does an aquarium heater use?

Not only do you have to connect the heater to an electrical source, but you also have to leave it on most of the time. This will certainly increase the electricity bill. But for how long?

Heating an aquarium can be expensive depending on the size of the tank. The larger the tanks, the higher the heat required and the more expensive it will be. In addition, a tropical fish environment generally requires a higher water temperature, which means that more electricity is spent on raising the heater temperature.

In general, a 30 gallon tank heated to 72 ° F or 22 ° C will consume approximately 110 kWh. You can calculate this rate based on the size of the tank to guess how much electricity the tank will use to warm up.

The same tank, if heated to 82 ° F or 28 ° C, will consume around 440 kWh per year, which is 4 times more.

In general, it is not possible to provide an exact number of how much the electricity bill will cost for the aquarium tank. But with the tank size and temperature set, some assumptions can be made based on the information provided above.

 

conclusion

From the list above, you can now easily choose the best aquarium heater. Many people who have used them have always ended up with high quality products that always offer performance.

You can be the next one to keep your fish at the right temperature to survive. Go ahead and choose the one you think is the best.
