A power outage is something you don’t want to encounter with your aquarium or aquaponics system. When the power goes off, the aquarium stops circulating water, heating it or providing any other form of care for your fish. Even with a backup generator, you need to make sure that it is working properly and not overheating.

First, always check with your local electric company when you lose power to see how long it will take before the electricity comes back on. Second, don’t panic! When a power outage occurs, it’s always the best idea to wait for power to be restored before doing anything major to your fish's home. Fish, however, are living creatures and need care during a power outage as well. To ensure the safety and health of your aquatic life during a power outage, it is important to take the following steps:

  • Unplug Electrical Equipment: It is a good idea to unplug any aquarium-related equipment that is plugged into an outlet. This includes lights, filters, and heaters. This will help reduce the risk of electrical surges when power is restored.
  • Prepare a Backup Plan: Have a backup plan in place in the event of a power outage. Consider adding battery-powered air pumps and air stones to your tank which can help ensure there is enough oxygen in the water.
  • Have Containers Ready: To help keep your aquarium water from getting too cold, have several containers filled with warm water ready to go.
  • Check the ammonia and nitrate levels in the tank to make sure they are stable. Monitor your aquarium closely and be prepared to take action quickly in the event of a problem.
  • Insulate the tank: Adding insulation to the tank can help to retain heat and keep the water temperature at a consistent level. You can use blankets, towels, or any other type of insulation material.
  • Feed the fish a small amount of food to help reduce their waste levels.
