Countermeasures for Power Outages in Aquariums

Power outages pose significant concerns for aquarium enthusiasts. When a power outage occurs, the circulation of water is compromised due to the stoppage of filters and pumps, potentially affecting the survival of fish and other aquatic organisms. Additionally, the decrease in water temperature due to power outages must also be taken into consideration. Here, we introduce measures to maintain the ecosystem of an aquarium during power outages.

Use of Generators

Let's consider the use of generators. When a power outage occurs, essential equipment within the aquarium ceases to function. In particular, the halt of filters and pumps impedes water circulation and oxygen supply, greatly affecting the health of organisms in the tank. Therefore, it is necessary to utilize generators to power these devices during power outages.

In our region, power outages occur almost every winter. We have experienced short outages lasting several hours and even longer ones lasting up to four days. As we began caring for marine fish and corals, we decided to purchase a generator capable of running for extended periods. Although it emits some noise, during the four-day power outage this winter, without the generator, we might have lost everything. We made the purchase before the outage, ensuring smooth operation. We protected the generator from rain and snow using a tarp, and since the generator's cord prevented the door from closing when brought indoors, we sealed around the door with duct tape. This generator not only powers the aquarium but also other electrical devices such as desk lamps and laptops, brightening the room and lifting our spirits. However, it is important to handle the generator properly as incorrect usage can pose dangers.

Protecting the Aquarium with Styrofoam or Blankets

As power outages can cause a rapid drop in aquarium water temperature due to decreasing room temperatures, it is crucial to cover the tank with styrofoam or blankets. Using these materials can prevent rapid fluctuations in water temperature, reduce stress on organisms, and increase survival rates. This measure is particularly effective in cold regions.

In our case, during the onset of a power outage while setting up the generator, we surrounded the aquarium with thick styrofoam we had saved from disposal, using duct tape. We left gaps without fully sealing the top of the aquarium and placed the styrofoam. We hoped this would prevent a rapid decrease in water temperature. We also expected that turning off the electricity when refueling the generator would prevent a drop in water temperature.

Withholding Food

During power outages, the halt of filters and pumps disrupts water circulation, potentially causing a rapid deterioration in water quality if food is provided. By withholding food, water quality can be maintained, protecting the health of fish and other organisms. While the duration of withholding food depends on factors such as the types and sizes of organisms and the size and condition of the tank, generally, refraining from feeding for several days during a power outage is advisable. However, it is essential to consider the health of the organisms and assess whether feeding is necessary. Monitoring the situation during the outage and ensuring water quality is not deteriorating are also important.

Points for Proper Generator Use

Place the generator in an appropriate location:

It is important to use the generator outdoors with sufficient ventilation. Avoid indoor use to prevent the risk of carbon monoxide poisoning.

Fuel management:

Ensure proper fuel supply to the generator and check the fuel supply regularly. It is also important to prepare spare fuel for long power outages.

Regular inspection and maintenance:

Generators require regular inspection and maintenance. Check engine oil and coolant levels and replace or replenish them as needed.

Prevent moisture and water ingress:

A tarp can help protect the generator from rain and snow. Since generators can pose a danger when combining water and electricity, using a tarp to prevent moisture and water ingress is crucial. Avoid completely covering the generator, as sufficient ventilation is necessary. Cover the top and partially cover the sides to ensure proper exhaust gas discharge. This way, the generator can be protected from rain and snow while ensuring safety.

Fire and electric shock prevention:

Generators generate high temperatures, so spilled fuel or oil can cause fires. Also, operating the generator in wet conditions or improper connection of power cables can pose a risk of electric shock, so pay sufficient attention.

Proper load management:

Calculate the power consumption of devices connected to the generator and ensure they do not exceed the generator's capacity. Overloading can lead to generator failure.

In our case, we disconnected the aquarium and generator plugs each time before turning off the generator to refuel, as a safety precaution.

It is important to follow these points to safely and effectively use generators and ensure that necessary equipment operates properly during power outages.

Power outages can be a serious problem for aquariums, but taking appropriate measures can minimize damage. We hope the measures introduced in this article will be helpful to everyone.
