How to keep your aquarium cool during an Emergency ?

Living in a tropical country like in Singapore, there will chances that we encounter some issue with the temperature of our tank rising either due to a chiller break down, power failure or pump failure.

In a marine tank environment, a escalating water temperature if it is not handle fast enough, it could be devastating resulting in a total tank crash or fish / coral causality.

It can be quite a challenge to keep an aquarium cool

Yes, we are living in a hot topical country, it is not easy to keep the aquarium cool. But during an emergency, we can help to keep our aquarium cool by using one or some of the follow method ;

Method 1: Fans – These are a great way to cool your aquarium tanks. The good thing about them is that they are a very inexpensive method that can be used.

There are many choices of fans that are available and these include fans that can be attached to the canopy, as well as fans that can be mounted to the tank rim.

Fans also help in cooling the aquarium as they blow air over the water surface. As a result, an increase of evaporation takes place in the tank. And this in turn cools down the tank. This is a process that is known as evaporation cooling, and it serve as a very good backup for use during emergency situation to help keep the water cool.


Method 2: Keep only minimum pump running – A lot of us might not have notice but one of the key source of heat in our aquarium water is from the various pump / power head we use for our calcium reactor, phosphate reactor, return pump ect… By minimizing the use of the pump , keeping the water running only on one return pump running or wave maker running , it will help to reduce the heat being introduce into the water until the chiller is repair or replaced. Remembering that a DC return pump run cooler comparing to a AC return pump, thus if you have two return pump use the DC pump instead of the AC one.

Method 3: Air Pump – Making use of a strong air pump to aerate the tank during a power outbreak or chiller failure not only help to keep the livestock alive, it also help to keep the water cool . The air pump will helps in increasing the exchange of gases that are taking place on the water surface. And in this process, heat exchange will also take place and this will cool down your aquarium.


Method 4: Floating Ice – A big advantage of this method is that it is a very inexpensive one and could be available instantly in any emergency situation. It is thus advisable to keep some of those bottle with water stored in your freezer as standby for any emergency situation.


Method 5: Open the tank covers – If you keep your aquarium covered, open the covers. By allowing more air exchange on the water surface , it will help cool the tank as well and if your tank is placed next to a window, remember to cover it up to avoid all direct or indirect heat source into the water.

What can you do to avoid such situation ?

  • Consider setting up a battery backed up wave maker that kick in during a power failure.
  • Consider switching from a AC pump to a DC pump since DC pump run cooler.
  • Consider setting up a power failure notification or controller that help notify you in the event of emergency.

Above are some of the situation that we can use during an emergency situation of power failure, or chiller breakdown to avoid any tank casualty until power is restored or chiller is replaced.
