This method is best for cooling the water gradually over several hours. If your tank is large, you may need more than one ice pack to achieve noticeable results.

Remember that ice packs should never be directly placed in the water without wrapping them first. The extreme cold can shock the fish. While this method is helpful in emergencies, it’s not a long-term solution for preventing overheating.

Install a Reflective Insulation

Using reflective insulation on the tank’s sides can help reduce heat buildup by reflecting excess heat away. This method is especially effective if your tank is located near a heat source. It helps maintain a more stable and cooler environment inside the aquarium, reducing the chances of overheating.

Reflective insulation materials are easy to apply and can be found at most home improvement stores. They are lightweight and don’t require much maintenance. Simply attach the material to the tank’s exterior, and it will reduce heat absorption from the surrounding environment. This is a cost-effective solution to maintain cooler water temperatures.

Adjust the Lighting Schedule

Adjusting your aquarium’s lighting schedule can have a noticeable impact on temperature control. Neon Tetras are not fond of direct heat from lights, so reducing lighting hours or switching to low-heat LED lights can help regulate the temperature.

Keeping the lights off during the hottest part of the day helps prevent the water from heating up too much. For a more energy-efficient solution, consider using timers for your lights, ensuring they turn on and off at specific times each day. By controlling the light exposure, you can maintain a more consistent temperature for your fish.

Monitor Room Temperature

Room temperature plays a significant role in the overall temperature of your tank. A room that is too warm can cause the water temperature to rise, leading to discomfort for your Neon Tetras. Keep an eye on the surrounding temperature to help avoid these issues.
