How to Choose the Best 5 Gallon Fish Tank Heater for Your Betta Tank Buyer’s Guide:
You’ve got your very own 5 gallon fish tank, and now you need to keep it alive with a heater! Or perhaps you want to be able to keep your 5 gallon tropical fish tank warm all year round? Whatever the reason for choosing a heater for your pet tank or aquarium, there are some important factors to take into account before making your purchase.
Otherwise, you may end up spending more than necessary on something substandard. For many people (such as myself) having a 5-gallon fish tank is the start of their journey in the hobby. Those who choose an adjustable heater must be sure that it includes information about its settings in the owner’s manual. This will help you know what type of tank it is designed for and at what temperatures your new 5-gallon fish tank should be kept.
Wattage and Tank Size:
Smaller tanks need smaller heaters. Bigger tanks need bigger heaters. A 5-gallon tank with a 15-watt heater will be underpowered whereas the same heater in a 10 gallon tank might be overkill. So when it comes to power, follow your fish tank size and apply that information to your heating unit choice.
The water temperature of some tropical fish species changes daily based upon their environment and activities, so an adjustable aquarium or 5 gal fish tank heater is essential for keeping them alive and healthy long term. If you live in colder temperatures or want to keep more than one variety of tropicals (seriously?) then you should consider at least getting an adjustable heater so you can alter the set point as the seasons change.
A good heater will have an adjustable temperature control to accommodate any type of tropical fish. It’s also important to note that these should not be used for Koi or other coldwater species. These are usually sold in settings ranging from 75-82 degrees Fahrenheit. Many online reviews will stress issues with the on/off switch and how long it may take your water temperature to rise after turning it on…so if this is a deal breaker, look elsewhere!
Thermostat Adjustability & Readability: The problem with many heaters is that they do not provide the ability to adjust them once they break down (which is very common). You should look for something with positive feedback on the internet to ensure that replacement parts are available and affordable. These can be especially useful if you live in a cold climate with temperatures below freezing during the winter months, or enjoy keeping tropical species throughout the year.
Knowing how accurate your thermostat is will be one of your most important considerations when buying a 5-gallon fish tank heater. Buyers who need specific temperature control for their tropical fish or other water creatures should opt for something that has clear readouts that they can depend on daily. Many people are turned off by heaters that have an inaccurate reading which may lead them to overheat their tank too much!
Safety Features: Along those lines…it’s very important to know what safety features a 5-gallon fish tank heater offers. Buyers need to know that the heater has a safety mechanism in case of power surges or other issues that could lead to dangerous water temperatures. Again, online reviews can be helpful here by offering specific examples and reports about the breakdowns they encountered with their 5-gallon fish tank heaters over time.
Temperature Safety Features:
Buyers should look for a thermostat on any heater purchased which will prevent the temperature from getting too high when these units malfunction, which is very common! Buyers should also opt for digital thermometers as opposed to analog designs just be sure you understand how they work and what may interfere with their accuracy.
Ease of Use:
Some people are extremely invested in the of their 5-gallon fish tank heater, and hold them to the highest of standards. Buyers should look for heaters that will not only provide accurate temperatures but also be easy to install or adjust. Buyers can often find these online in “how-to” videos which demonstrate how these are installed as well as their maintenance requirements (some need far more work than others).
Types of Small Aquarium Heaters:
Buyers can choose from five different types of heaters that have been specifically designed for 5-gallon fish tanks! They are:
Buyers should look to purchase an immersible heater which is made with a glass tube. These are smaller than submersible designs, and therefore more efficient when it comes to how they heat your water. Buyers will need to purchase a thermostat adapter or other safety mechanism on these in order to ensure maximum safety. Buyers may also want to consider adding a thermometer so as not to overheat or underheat their aquarium; changing the temperature by just one degree can make all the difference to your fish’s survival.
Buyers looking for a 5-gallon fish tank heater with far more power than regular immersible heaters will want to consider purchasing a sump heater. These are designed to fit into the sump of your aquarium, and can actually be attached to an outside wall or other part of your fish tank’s frame if necessary. Buyers should also consider these if they have multiple tanks that they’d like to keep at consistent temperatures.
Buyers who simply need something compact but effective may prefer an under-tank heater, which is relatively inexpensive and easy to install on top of or underneath their existing 5-gallon fish tank space! Buyers must remember that this design does not provide water circulation…so it is advised that they purchase a thermostat in order to minimize temperature fluctuations and provide the most consistency possible.
A 5-gallon fish tank heater that is more like a classic aquarium filter will be considered an undergravel heater, which essentially rests below the gravel flooring of your tank (not necessarily underneath the actual 5-gallon fish tank). Buyers should make sure their heating device has enough power to meet their heating requirements throughout all parts of their water habitat! These can take up quite a bit of room under the gravel without being incredibly efficient…but they will still do well with smaller tanks or bowls. Buyers should also consider purchasing an “extras” kit if one isn’t provided with his purchase.
Commonly Asked Questions:
What is the best betta tank heater?
Buyers who are looking for the best betta tank heater will want to consider purchasing a compact, affordable unit that is tailored for their 5-gallon fish tank. Buyers can look to purchase an under-tank heater or one of the more powerful sump heaters if they have multiple tanks in separate areas of their habitat
Can you put a heater in a betta bowl?
Buyers should first check the wattage and temperature rating on any 5-gallon fish tank heater which they plan to use with a betta bowl. Buyers must also remember that some heaters simply cannot be used with bowls at all! Those who wish to find out whether or not this is possible may want to contact the manufacturer directly.
How do you put a heater in a betta tank correctly?
Buyers should first make sure that their heating device is compatible with their 5-gallon fish tank! Buyers can also check to see if the manufacturer has any recommendations for how long they should leave it before placing any of their fish into the water.
Do I need to do any maintenance to my 5 gallon tank heater?
Buyers must remember that keeping proper temperatures within their tanks does more than provide a more hospitable home for their Betta (or other species)! Buyers must have the right temperature and chemistry levels in order to keep Bacteria thriving…which keeps your water clean, healthy, and safe for all of your aquatic pets! Buyers who want these healthy conditions will want to make sure they are cleaning their 5-gallon fish tank heater regularly, as well as checking the temperature settings to ensure that they can meet your needs. Buyers may also want to consider purchasing an air stone or other filtration system, which will help keep water oxygenated and healthy for your little pet!
Why Should You Use a 50 Watt Heater?
Buyers who want more power (and precision) from their 5-gallon fish tank heater will be happy to know that there are many units that provide up to 50 watts of heating power! Buyers should also note that higher wattage heaters tend to cost less per watt than lower ones…which means you get more bang for your buck!
Why Should You Use A Submersible Heater?
Buyers who want the most versatility from their 5-gallon fish tank heater will be happy to know that there are submersible tanks available! Buyers can literally drop this heating device right into their water habitat and keep it there without worrying about it taking up space under a gravel flooring, and without having to buy any additional filtration systems. Buyers should remember that this sort of waterproof heater is usually only ideal for smaller tanks (under 10 gallons), as keeping a larger aquarium or bowl at the appropriate temperature may need something bigger.
