How To Heat Up Fish Tank Quickly

Adjust the Room’s Temperature

If you are in a rush and want to have a prolonged impact on your fish tank water then it’s time to adjust the room’s temperature.

In colder months, this becomes one of the easier ways to help regulate the fish tank’s water temperature.

The idea is to use the thermostat as a way to control the fish tank’s water conditions. For example, if you have set the thermostat to 21-22 celsius then it’s time to crank things up a few digits. Continue to pay attention to the fish tank water after a few hours. It will also start to heat nicely.

Keeping the room’s temperature to a stable 21-22 degrees celsius will ensure the fish tank’s water temperature doesn’t plummet rapidly.

Of course, it’s important to keep an eye on the fish tank and make sure it is not overheating. This becomes a problem as the temperature rises outside your property.

You shouldn’t do this all the time but it’s important to make adjustments on the go. If you make adjustments to the room’s temperature, it’s a lot easier to control how cold the fish tank water is. Otherwise, it will get to the point where your fish tank water continues to get colder and colder with time.

Be diligent and make these adjustments right away. They are going to save you quite a bit of time as a fish owner.

Use a Warm Plastic Bottle

This is a trick that is used for those wanting a short-term solution for heating a fish tank.

In general, the “Warm Plastic Bottle” method works for a little bit but it won’t fix the root cause (i.e. external conditions). This method is going to ensure you have additional time to work a long-term solution for heating the aquarium.

So, what is this method all about then?

The premise of this method is to take a traditional plastic water bottle, pour freshly boiled water in, and seal it with a cap. After doing this, you are immediately going to place the water bottle inside the fish tank.

This will start to warm the fish tank water automatically. While it is not going to be rapid, you can continue to keep track of the water temperature and make further adjustments (i.e. add another water bottle).

It’s important to note, you should only do this when you have a few hours to spare. There should never come a time when you leave the fish tank with the water bottle inside. This could lead to a situation where the water becomes too hot.

While this is rare, you should always prepare for the worst and go for there!

You goal should always be to ramp up the water temperature when it drops. This means taking out a well-sized water bottle and placing it inside the fish tank. It will take a bit of time to change the water temperature inside a fish tank but it will work.

This is one of the best DIY methods in the world when it comes to warming a fish tank. Over time, you will start using long-term solutions but this is a reliable starting point. Start here and you are going to feel more than comfortable with the results.

Wrap the Fish Tank with Warm Blanket

This is another temporary solution and can be used in combination with the “Warm Plastic Bottle” method.

This is a straightforward solution and is just as you would imagine.

In general, you are going to heat a well-sized blanket that can wrap around the outer shell of your fish tank. This needs to remain near the base of the fish tank, so you can start heating the water without blocking your view.

Experts Say...
Heating up a blanket and wrapping it around the fish tank is a good DIY solution for short-term results.

In most cases, you are not going to have to worry about overheating the water in your fish tank. Instead, it is only going to work for a while before the results are going to start slowing down. A lot of fish owners realize this only works for 15-20 minutes before becoming ineffective.

The only time this method should be used is if you don’t have an automated heater for the fish tank. Since you won’t have a way to consistently heat the fish tank, this is an option that can be used. Continue to monitor the water during this process and take regular temperature checks to make sure you are on the right path.

If you feel this isn’t working as well, it is okay to add another warm blanket on top. This is going to add more heat into the mix leading to faster results.

Temporarily Position the Fish Tank Closer to a Vent

Where is your fish tank located in the room right now?

There are times when a fish tank is too far away from a vent. This is generally okay but it won’t be if the temperature is dropping and your water is becoming too cold. When this happens, it’s time to make immediate changes to your setup.

So, what is the right way to go as you learn to heat up fish tank quickly?

The goal is to position it close to a heating vent. This is going to allow the heat to come through and warm the fish tank for a bit. Please note, this shouldn’t be done for long periods because it may overheat the fish tank leading to unnecessary harm!

If you are going to be doing this make sure the temperature is increased slightly and you don’t put it right on top of the vent. It should be nearby providing more access to the warmer air being pushed through the vent.

It shouldn’t take long for the fish tank water to heat up. In most cases, you are going to start to notice a change on the thermometer after a few hours. This is more than enough to help regulate the temperature before you look towards buying a safe aquarium heater.

Find a New Room in Your Property

Do you have a different part of the house that is warmer than this one?

It’s normal to place a fish tank in a certain room based on preference. However, this doesn’t mean that is the hottest part of your property.

Walk around the home and see where you can position the fish tank to make sure its water is in good shape throughout the coming days.
