One way to warm up a turtle tank without a heater is to use an incandescent light bulb. The wattage of this type of bulb is high, and it produces a high level of heat, but it also emits UV rays. This method should be used only during the day and placed out of reach of the turtle. It will cost you more money than an incandescent light bulb, and it will cause the turtle to get burned.
Another option is to place a heat lamp in the turtle tank. Heat lamps produce UVA rays, which are important for the health of turtles. During the winter, they may suffer from respiratory illnesses if the water temperature is below 50 degrees Fahrenheit. However, heat lamps can be used in certain climates. In fact, some climates don’t require heat lamps to keep the turtle tank at a comfortable temperature.
Depending on the type of turtle tank, a thermal-resistant heater can prevent the water from getting too hot or too cold. You can buy one online or locally. Make sure to measure the size of the tank and buy enough styrofoam to fit. Secure it in place with an adhesive or transparent sellotape. If you don’t have any styrofoam, you can purchase black styrofoam instead, which is another great heat trapper.
When you choose to keep a turtle tank without a heater, you need to keep in mind that the temperature must be 73 degrees Fahrenheit. While adult turtles can live comfortably in a cooler temperature, baby turtles need a warmer tank. However, too much temperature can cause bacteria and other health problems. The temperature of the turtle tank should not be too high, since too high temperatures encourage the growth of bacteria and discourage basking.
If your turtles are not exposed to sunlight, they will start to feel the cold and will either hide in the bottom of the tank or start brumating. If you cannot provide this source of heat, you can purchase a heat lamp from Amazon for as low as $15. It’s also possible to find a heat lamp for under $20 on Amazon. But you must be sure to check out the label before buying one.
A turtle tank without a heater is not as difficult as some people think. You just have to remember that turtles are dependent on their owners for their needs. During cold months, they cannot find a heat source on their own. A heater helps you control the temperature in the tank and prevents them from getting sick. So, if you live in a region where temperatures fluctuate wildly, a turtle tank heater is an absolute must for your turtle.
