Once it is in your tank, it is still easy to access it using the large control knob you can find on its top end. Reading the temperature monitor is easy because of a clear monitoring light – the red light is for heating, whereas the green light tells you about the current temperature of the aquarium.

Overall, the heater works great for proper temperature control, but it's worth mentioning that some users have complained about it overheating quite quickly.
That's not something to worry about though, but it's still a good idea to use a thermometer to achieve the right temperature setting and avoid overheating.
You have to consider a number of things to decide where you can place your fish tank heater. For instance, the size matters a lot, which ultimately depends on the size of the tank. Ideally, you should choose a heater considering how many gallons in your tank. For each gallon of water, there should be a heater of up to 5 watts. It means you should have a 100-watt heater for a 20-gallon aquarium.
However, you should go for two aquarium heaters if you have a tank larger than 40 gallons. In this case, you should place a heater at opposite ends of your tank. You can opt for two 100-watt heaters to maintain a degree of uniformity in water temperature. Having two aquarium heaters is also a good idea because one will keep working even if one stops functioning for any reason whatsoever.
To select the best place for your heater for aquarium, you should also consider heat circulation and water flow. For instance, it is a good idea to place your heater where you notice high water flow, but at the same time, you should ensure that it doesn't suck newly heated water into the bio-filter. It is important because failing to consider this point would overheat your beneficial bacteria.
In this situation, you can try another option, which is to place your heater for fish tank near the filter outflow. This way, the heater will send the warm water in the circulation current into normal water. Similarly, you may want to place your heater horizontally above the gravel – it should be close to the filter discharge, but ensure that you're going for fully submersible aquarium heaters.
A good idea is to take an air stone and add it under the filter intake. This is to ensure that denser cool water goes to the bottom of the aquarium. Moreover, you should bear in mind that you will get good results when you opt for a fully submersible heater. It will provide you with more freedom of placement as compared to a partially submersible aquarium heater.
While it is easier to find a suitable place for your fully submersible aquarium heater, keep in mind that it requires more maintenance, which is why it is a good idea to replace it at least once a year for optimum performance. To avoid maintenance problems, you should put your money on a high-end submersible heater, as it is designed to last for many years.
Yes, fish tank or aquarium heaters with temperature control features are generally quite safe to use. However, it is still important to take some precautionary measures to avoid dealing with an unexpected situation. You can now find a variety of heaters designed for different types of aquarium, and high-end aquarium heaters with lifetime warranty are usually quite safe to use.
Here are a few tips to continue using your heater safely while keeping your tropical fish happy.
Maintaining the right water temperature is important and that makes your aquarium heater a critical piece of equipment. Therefore, you should never try to cut corners here and opt for the best quality heater with top-notch heating element to continue enjoying a great performance. Moreover, you should stay away from trying DIY heater repair, as it is sometimes better to discard the old one and switch to a newer model for a safer performance.
In order to select the right sized heater, you should consider the water volume of the fish tank first. Similarly, considering the desired temperature and the average room temperature is equally important.
In most cases, the heater wattage should at least be 2.5 watts per gallon of total water volume in the fish tank. Sometimes, larger heaters are required for very large aquariums, and sometimes, it also depends on what water temperature you want to achieve. You can use multiple heaters to achieve the required temperature.
The temperature in the room where you want to place the aquarium needs to be considered always. For better adjustment, you should find the average room temperature and then subtract the number from the target temperature you want to have in the aquarium water.
Though investing in a heater is probably the best way to heat your fish, you can surely find some alternatives to try when your heaters fail and you're looking for a replacement. Here are some options to consider:
Overall, you should make no compromises over quality when buying the best fish tank heater. Be sure to pay attention to the size of your aquarium as well as the number of fish you have. Also, put your money on a high-end heater to enjoy great performance without any safety issues.
