I get it; you have a fish tank. Now what? Well, there are so many things that need to be done for your new pet friend! When you have a fish tank, having a heater can be beneficial to your fish.
A 50-watt heater has been designed specifically for small tanks between 5-15 gallons in size. Investing in a 50-watt aquarium heater would be wise for keeping your fish happy and healthy! So if you have a larger tank, I recommend going with something bigger.
If you are looking for the best 50W aquarium heater, look no further! I have reviewed some of the prime models on the market to help you decide which is right for your needs.
A quick comparison of my top 3 choices:
Best 50 Watt Aquarium Heater Review
Hygger Titanium Tube Submersible Aquarium Heater
The hygge Titanium Tube Submersible Aquarium Heater is made of titanium, which is very durable and heat resistant. The heater has a separate temperature controller that allows you to adjust the temperature between 32-104°F. It can be used in all aquarium setups of 5-10 gallons capacity except for acrylic tanks.
The heater is furnished with a separate controller that has dual displays. Two digital screens show what you set as well as what’s the real-time tank temperature. So there’s no need for an additional thermometer! In addition, you can adjust the temperature without removing it from your tank.
The built-in thermostat is designed to maintain unmatched accuracy, and that’s +/- 0.5° C. It also ensures automatic heater on/off based on the set point.
The manufacturer’s recommendation is to place the heater horizontally. You can easily do that with suction cups provided. The power cords and cables are long enough, so installation is also quick-paced.
A cautionary note is, don’t forget about attaching it to your controller! Otherwise, the heater will continuously heat the water without stopping. Moreover, it’s always best to read the user manual properly before installing it in your aquarium.
If you have a small fish tank and are looking for a heater to fit your small space. This is perfect! And it will fit perfectly on the bottom of your 10-gallon tank. In addition, you’ll have one-year free replacement benefits for damaged items.
Pros
- Made of Titanium, high precision heater
- It contains a separate temperature controller
- Large heating range (32 to 104°F)
- A reabiable thermostat ensures automatic on/off
- Ideal for all setups, except an acrylic tank
Cons
- Suction cups are not robust
- Some users find instructions are hard to interpret
Fluval M50 Submersible Heater
Fluval’s M50 submersible heater is the perfect choice for your 10-15 gallons aquarium. This compact, sleek and aesthetically-pleasing design will fit nicely into any decor. In addition, the Fluval M50 features a mirrored finish that reflects light, adding to its elegant appearance.
The Fluval M50 Submersible Heater is easy to use. Its adjustable temperature dial on the top allows you to set the desired temperature of your tank between 66°F and 86°F.
In addition, this aquarium heater has an automatic shut-off security feature that turns on when the desired water temperature level has been reached. So you can enjoy your fish without worries!
The heater has an indicator light that demonstrates an active state. Calibration is also easy; however, a couple of failed attempts is not uncommon for a beginner.
Unfortunately, the heater has no built-in heater guard and a dry-run sensor. Therefore, make sure to keep it submerged when the power is on. However, with its 03-year warranty period, the Fluval M50 is a smart investment for any aquarium to get the job done.
Pros
- It can be used for both salt and freshwater aquarium
- Sleek, elegant design
- Automatic shut-off
- Adjustable temperature dial
- Provides 03 years warranty
Cons
- Relatively longer and without a built-in heart guard
Eheim Jager Aquarium Thermostat Heater
The Eheim Jager Aquarium Heater is the perfect choice for any tank up to 15 gallons, with an adjustable temperature range from 65-95 degrees Fahrenheit.
When you turn on your heater, the green light will come on and indicate that it’s running correctly. The temperature can be adjusted by a temperature dial located on top of it, and it has two parts. The blue one sets your desired warmth, while the red one is used for calibration.
For a beginner, calibration can be a little confusing in the first instance. For example, suppose you have set 78 degrees by turning the blue dial, but the tank temperature reads consistently 75 degrees. Then, it has to be calibrated by turning the red indicator dial until the arrow indicates 75° F.
The heater’s glass jacket increases its heating surface, making it more effective at giving off heat, and maintains a steady temperature in aquariums. In addition, the Eheim Jager Aquarium Heater has a dry run sensor, which protects it from running dry when not in use. This means that the heater shuts off instantly when it’s not submerged in water.
It is also equipped with mounting brackets that allow you to place the unit wherever you want. Moreover, they can hold securely without the risk of falling down due to gravity or slipping around on smooth surfaces!
The heating tube is larger than the standard heaters available in the market. Consequently, it may be challenging to find a guard that will fit on its long and narrow shape because the heater doesn’t have a built-in heater guard. The heater tube measures 20″ in length with a 1/8th inch diameter at both ends, so ensure your tank has plenty of depth before buying one!
Pros
- Easy on the wallet
- Light indicates heater status
- The temperature dial is large and comfortable to read
- Maintain consistent temperature
- It has a built-in dry run sensor
Cons
- Large size makes placement a bit tricky
- Calibration can be difficult for beginners
- No built-in heater guard
Aqueon Adjustable Pro Heater
The Aqueon Adjustable Pro Heater has an electronic thermostat accuracy of more or less 1 degree Fahrenheit. Meaning that you can maintain the perfect water parameters for your fish!
Moreover, it allows you to set a suitable temperature for your aquarium in a range of 68 to 88 °F. This makes it perfect for freshwater and saltwater marine life habitats alike, which is why I think this heater deserves a spot in any aquarium enthusiast’s fish tank.
Thanks to its strong suction cups, the Aqueon Pro Heater can be installed either horizontally or vertically on your tank. So you don’t have to worry about it being all over the place. It’s also fully submersible, so that means this heater will not work if there is no water around!
I also love that it has a convenient LED light display. When the indicator light is red, you know your device’s heating; on the other hand, green means not heating! That’s a convenient way to find out if your device is working or not at any given time.
It has a protective feature when it overheats. The heater automatically stops in case of overheating and immediately restarts once the temperature returns to normal, which means you don’t have to watch your aquarium heater like a hawk!
The added benefit is that this heater has a strong heating element that guarantees durability and longevity. It also distributes heat more evenly, so you get fast-acting warmth in no time at all!
Pros
- Affordable.
- It can be placed both vertically and horizontally.
- An indicator light turns on while the heater runs.
- It has a robust and durable shell
- Its automatic shut-off and restart functions make it very handy.
Cons
- Some users remark that the thermostat is not very accurate.
