Things You'll Need
- Nylon netting
- Small electric fans
- Live aquarium plants
Instructions
Close shades and curtains in the room with the aquarium. Keep tank lights on for the minimum time needed for the health of your fish.
Remove the aquarium lid or open all of the covers to release heat from the water. Drape nylon netting over the tank to keep jumpers from escaping.
Set a small electric fan near the open aquarium and direct airflow across the top to blow the heat away as it rises.
Keep your aquarium understocked during hot weather. The more fish in the tank, the more oxygen is needed to supply them.
Crank up the air pump to its maximum capacity to add extra oxygen to the water and help heat exchange at the surface.
Plant and float as many live plants in your aquarium as you can to add oxygen.
Remove uneaten food and debris, which quickly rot and remove oxygen from the water.
