Here is a rundown of each (good and bad) and also what you should look out for.

Best 50 WATT Aquarium Heaters For 10 Gallon Tanks

Keep in mind that some of these come in different watt models but we are mainly focusing on options for 10 gallon tanks / 50 watt heaters here;

1. Cobalt Aquatics Aquarium Heater

A small and powerful heater, this one does come in a 50 watt model, but can also be purchased in a 75 or 100 watt option as well. It’s a nice option to go with because it is extremely flat and streamlined. It barely takes up any space at all inside of a tank, and therefore reserves valuable real estate for fish.

It comes with an easy one touch set system, so you can set the temperature with ease. This heater has a range of 30 degrees, and can heat your tank to as little as 66 degrees or as high as 96 degrees (Fahrenheit), although you probably won’t ever require such high temperatures.

The LED display on this thing displays both the set temperature and the current water temperature with fairly good accuracy. It’s fully submersible, but beware that it’s not the most durable option in the world. It does come with thermal protection circuitry to keep your fish safe and to keep this thing in working condition.

Pros

  • Space friendly.
  • Wide temp range.
  • Easy to use.

Cons

  • Limited durability.
  • A little slow .

2. Aqueon Pro Submersible 50W Heater

This is another good fully submersible 50 watt aquarium heater to go with. It should not take long for this thing to achieve the desired water temperature. The Aqueon Pro 0W Heater features a very slim, sleek, and rounded design which is very space friendly and does not take up lots of space within the aquarium.

It’s great for small tanks with limited room to spare. What is nice about this thing is that it is labeled as being shatter proof and nearly indestructible, which is indeed true for the most part.

The Aqueon Pro allows you to set the temperature between 68 and 88 degrees, which is Ok, not great, but Ok. Use the knob to adjust the temperature.

Beware that this thing does not have a display and does not inform you of current tank temperature. It has an auto-shut off feature to prevent heat damage, but it is known for getting quite hot and having to take some breaks.

Pros

  • Very durable.
  • Easy to set.
  • Space friendly.

Cons

  • Does not display current temp.
  • Has some overheating issues.

3. Hydor Submersible Aquarium Heater

Yet another good option to keep in mind, the Hydor Submersible Heater comes in many power options including 25, 50, 100, 150, and 200 watts, making it a good option for virtually any size of aquarium.

This thing is labeled as being shock proof to keep your fish safe, as well as shatterproof, but beware that it is made of glass, so a big bump bight be able to crack it.

What is also neat about this heater is that it can be positioned vertically, horizontally, or fully submerged, plus it has a very sleek and slim profile that makes it great for aquarium that have limited room to spare.

It comes with a graduated scale for precise temperature setting and has a decent temperature range too. It actually displays your setting in C and F to ensure that you can understand it with ease. Although this thing does not display current tank temperature, it does regulate output based on your settings.

Pros

  • Space friendly.
  • Very user friendly.
  • Decent temperature range.

Cons

  • Not terrible accurate.

4. Tetra HT Submersible Heater

If you need a small aquarium heater, one with a thin, rounded, and sleek profile that will barely take up any space inside of your small tank, the Tetra HT Heater is a nice option to keep in mind.

It can be installed vertically or horizontally, and has no problems being fully submerged in water, not to mention that it barely takes up any space within the tank. What’s nice here is that it comes with an indicator light to let you know when it is running, and one to tell you when the proper temperature has been achieved.

The Tetra HT does however not allow you to set your own temperature. This is not an adjustable heater and will always attempt to maintain the water at a steady 78 degrees.

However, it’s not the strongest option around, and if your aquarium does not have a good, it might have a hard time keeping up. It comes with a suction cup for easy mounting, which is always nice.

Pros

  • Very easy to mount.
  • Space friendly.
  • Consistent temperature.

Cons

  • Does not allow you to set the temperature.
  • Limited durability.

5. HITOP HP-608 Heater

This particular heater is great for smaller tanks, but do keep in mind that it also comes in a 100 watt and a 300 watt option for larger aquariums.

The HITOP HP-608 is not very long or thick, and it features a really space friendly design so it does not take up too much space in an already tightly packed aquarium. The glass used here is very thick, it protects the water against shocks, and is nearly impossible to break.

It is definitely a very durable heater that should last for a long time to come. This thing comes with a suction cup for easy mounting, and can be mounted either vertically or horizontally, all while being fully submersed of course.

Now, it does not display the current tank temperature, but you do get a low grade thermometer on the side. You can set this heater to heat between 61 and 90 degrees, so it does have a good range, but it is not the most accurate option in the world.

Pros

  • Easy to mount.
  • Space friendly.
  • Very easy to use.
  • Durable.

Cons

  • Not the most accurate option out there.

6. Uniclife Submersible Heater

The Uniclife heater is a nice 50 watt heater, one that also comes in a 25 watt option for even smaller tanks. For one, this thing is not the most durable in the world. Yeah, it is labeled as being bomb proof, or something like that, but in reality, it is not super durable.

We just wanted to get that out of the way. Other than that, this thing is fine for smaller aquariums. The Uniclife comes with suction cups and mounting gear to help make life a bit easier.

Moreover, it can only be mounted vertically, but we don’t think that this is a big deal, as people usually mount them vertically anyway. This thing does not come with its own display or temperature readout, but it does come with a little thermometer on the side, albeit not a great one.

You can adjust this heater to heat between 61 and 90 degrees, but it is not all that accurate. It is accurate enough, but achieving a +/- F range is probably not going to happen, as it is only accurate to within a few degrees.

Pros

  • Very space friendly.
  • Very easy to mount.
  • Easy to set the temperature.
  • Includes a thermometer on the side.

Cons

  • Limited durability.
  • Limited accuracy.

7. AquaTop Quartz 50 Watt Heater

This is another standard yet effective 50 watt aquarium heater to keep in mind. It is great for any tank up to 10 gallons, especially ones with hoods. It is one of the smaller and more space friendly options out there, so it won’t eat up too much valuable tank space.

Moreover, it is very easy to mount with the suction cups and can be mounted vertically or horizontally if desired. It has a simple knob that is used to adjust the temperature, and the scale comes in both F and C for your convenience.

The AquaTop Quartz has a range from 68 to 93 degrees, which should be more than good enough for any tank. In terms of durability, this heater is about middle of the line. It’s not super durable, but also not fragile either.

Pros

  • Good for small tanks.
  • Easy to mount.
  • Easy to set.
  • Fairly durable.

Con

  • Not the most accurate.

What Makes A Good 10 Gallon Aquarium Heater?

Before you go out and buy any aquarium heater, there are a few considerations that you should keep in mind.

  • A heater that displays both the set temperature and the current temperature is always useful, although smaller options will usually only display the set temperature.

  • A temperature regulator is important, which makes the heater turn off when the set temperature has been achieved.

  • You do want the heater in question to have a decent temperature range, ideally between 66 and 90 degrees at the very least. Moreover, one that comes with an easy set system is nice too.

  • The aquarium heater in question should be fairly small so it does not take up much space, and should allow for both horizontal and vertical mounting, preferable with suction cups.

  • Durability is a key factor too. You need something tough that won’t shatter, something with good circuits that won’t overheat, and something that is not going to fry your fish.

Conclusion

As you can see, as long as you keep an eye for a few main considerations, there are many good 50 watt heaters for 10 gallon tanks out there but these particular 7 are the ones that we personally felt deserved a mention. Either way just do your research and you will be fine.
