What You'll Learn
Use a submersible heater
To heat a plastic aquarium, you can use a submersible heater. These heaters are installed horizontally near the bottom of the tank, or they can be positioned vertically if that is your preference. It is important to keep decorations away from the heater so that water can circulate freely around it. A good rule of thumb for aquarium heaters is 5 watts per gallon for aquariums 55 gallons or smaller, and 3 watts per gallon for those over 60 gallons.
When making adjustments to your heater, it is important to allow several hours before checking the results. You should not change your aquarium's water temperature suddenly or dramatically, as this can stress your fish. Always unplug your heater and let it cool for at least 30 minutes before removing it from the water. After installing your heater in the aquarium, you should wait at least 30 minutes before plugging it in.
It is also important to consider the placement of your heater inside the aquarium. Position the heater near a filter inlet/outlet or a circulation pump to ensure even heat distribution. Avoid placing your aquarium near a drafty location such as a door, an uninsulated wall, or a cold basement. If you do, you may need a second heater and you may also need to adjust them more often.
Some people have expressed concern about the safety of using a heater in a plastic aquarium, as there is a risk of melting the plastic. However, others have reported using heaters in plastic containers without any issues. It is important to make sure that the heater is not laying against the plastic and that there is water circulation to prevent the heater from getting too hot.

Understand the correlation between heat, water and flow
Understanding the correlation between heat, water, and flow is essential when heating a plastic aquarium. Water is a crucial medium for transferring heat, and its high specific heat capacity means it can absorb or release significant amounts of heat energy without undergoing drastic temperature changes. This property of water is essential for maintaining a stable temperature in an aquarium, as sudden temperature fluctuations can be harmful to aquatic life.
The relationship between heat and water is complex and dynamic. As water temperature increases, its viscosity decreases, leading to reduced friction and improved flow. Conversely, as water temperature decreases, viscosity increases, causing higher friction and impeding flow. This phenomenon is due to the varying energy levels of water molecules at different temperatures. Warmer water molecules have higher energy, allowing them to move more freely and resulting in reduced friction.
In the context of an aquarium, water flow plays a critical role in maintaining water quality and supporting the health of aquatic organisms. Water flow helps distribute heat evenly throughout the tank, preventing localised hot spots and ensuring a consistent temperature. Additionally, adequate water flow ensures proper gas exchange, nutrient uptake, and waste removal, all of which are essential for the well-being of fish and other aquatic life.
When heating a plastic aquarium, it is important to consider the placement of the heater to optimise water flow and temperature distribution. Submersible heaters are a popular choice as they can be placed almost anywhere in the tank, allowing for flexibility in creating the desired flow patterns. However, it is crucial to ensure that the heater does not come into direct contact with the plastic surfaces of the aquarium to prevent any potential melting or safety hazards.
By understanding the intricate relationship between heat, water, and flow, aquarists can create a healthy and stable environment for their aquatic pets. This knowledge enables them to make informed decisions about heater placement, water flow optimisation, and temperature regulation, ultimately contributing to the overall success and well-being of their aquarium ecosystem.

Heat a plastic container for water changes
Heating a plastic container for water changes can be a straightforward process, but it's important to take certain precautions to ensure the safety of your aquatic creatures. Here are some detailed instructions to guide you through the process:
Firstly, it's crucial to understand the correlation between heat, water, and flow. The relationship between water and heat is complex, and it varies depending on factors such as the type of water and the specific heat capacity of water. Water has a high specific heat capacity, which means it can absorb a significant amount of heat energy without a substantial temperature change. This is beneficial when heating an aquarium because it provides a stable environment for your aquatic creatures, preventing sudden temperature shocks.
When heating a plastic container for water changes, it's essential to choose the right type of heater. One option is to use a submersible heater, which can be placed directly into the water. These heaters are often made of glass and are adjustable, allowing for precise temperature control. Ensure that the heater is not laying against the plastic container, as direct contact may cause melting. Instead, maintain proper water circulation and keep the heater fully submerged when it is on.
Additionally, consider installing an inline heater module, which is a separate unit with input and output nozzles and a chamber for the heater. This setup allows for efficient temperature regulation as the water flows around the heating element before entering the aquarium. If you have large, aggressive fish, you may want to invest in a heater guard—a plastic cage that prevents the heater from being damaged by the fish.
It's important to regularly measure the water temperature in different areas of the container, including the top, bottom, and sides, using a handheld thermometer. This will help you ensure that the heat is distributed evenly and maintain a stable environment for your aquatic creatures.
If you're facing a power outage, there are alternative methods to heat the water. You can use hot water from a gas water heater or heat water on a gas stove to place into the container. Aim for a temperature between 100 to 120 degrees Fahrenheit (38 to 49 degrees Celsius) to maintain the aquarium water temperature at around 80 degrees Fahrenheit (27 degrees Celsius).

Use an external heat source
Heating a plastic aquarium requires careful consideration of the correlation between heat, water, and flow. The specific heat of water means that changing the temperature of your entire aquarium takes several hours, which is good because you don't want to shock your fish.
One option for heating a plastic aquarium is to use an external heat source. Before the invention of electricity, small gas burners were placed under the aquarium to keep the fish warm. These burners heated the specially designed heat-retaining bottoms of the aquariums. Modern aquariums are typically made of glass or acrylic and do not retain heat in the same way. However, you can still use an external heat source to warm the water in your aquarium.
If you have a gas water heater, you can use the hot water to fill bottles and place them in the aquarium to warm the water. Ensure that the water in the bottles is not boiling, as this may harm your fish. Aim for a temperature of around 100 to 120 degrees Fahrenheit (38 to 49 degrees Celsius) to maintain an aquarium temperature of about 80 degrees Fahrenheit (27 degrees Celsius).
Another option for using an external heat source is to heat water in a pan on a gas stove and then place it into bottles to warm the aquarium. You can also use electric hot water bottles, but be aware that these will not work during a power outage. To maintain the desired temperature in your aquarium, regularly test the water quality and be prepared to do extra water changes.

Insulate the tank and filtration
Insulating your plastic aquarium tank and filtration system is essential to maintaining the water temperature and reducing heating costs. Here are some instructive tips to achieve effective insulation:
Firstly, identify the areas of heat loss in your aquarium. Heat escapes through evaporation, and most heat loss occurs from the top of the tank. Therefore, it is crucial to prioritize insulating the tank's surface. Consider using a custom foam top or a thick towel on the hood to trap the heat inside the tank.
Next, focus on the sides and back of the tank. You can use various materials for insulation, such as foam, styrofoam sheets, or foamcore (plastic foam sandwiched between paper layers). For a more aesthetically pleasing option, you can create an acrylic cover for the back and sides of the tank, although this may be a bit more expensive. If you decide to use foam, consider adding a 1" layer of foam to at least the back of the tank, and you can insulate two or more sides if your tank is in a corner.
Additionally, reflective insulation, such as Reflectix, can be beneficial for reducing heat loss. This type of insulation is commonly used in walls and can reflect both heat and light. You can also use construction adhesive or silicone for a more permanent solution, as hot glue tends to pop off.
Finally, don't forget to consider the filtration system. Insulating the filtration unit can help maintain water temperature and improve energy efficiency. Ensure that the filtration unit is well-covered and insulated to retain heat.
By following these steps and prioritizing the areas of heat loss, you can effectively insulate your plastic aquarium tank and filtration system, creating a comfortable environment for your aquatic pets while also reducing your heating costs.
