Aquarium chillers are often needed when running a marine aquarium in order to reduce the ambient temperature of the water, especially during the warmer summer months if you have cold water fish.

There are 2 types of aquarium water chillers :

•  Drop-in, and

•  In-line chillers.

Drop-in aquarium chillers are extremely simple and work by having coils that you simply place in the sump and act to reduce the surrounding water temperature.

In-line aquarium chillers are slightly different in that they have internal cooling coils. In order words, they work by pumping the tank water through the coil where is it cooled and then returned to the tank at the lower temperature. While this sounds more complicated there is one advantage in using an in-line chiller over the drop-in variety and that is the 'in-line' chillers can be used externally. In other words you do not have to place them anywhere near the vicinity of the tank removing the need to have unsightly looking equipment near the tank. You can put the chiller in another room or in a cupboard the choice is yours.

In order to use an aquarium water chiller , however, a device called a 'temperature controller' is necessary. Again there are 2 types of controllers:

•  Single stage controllers which only control the chiller, or

•  Dual stage controllers which can manage BOTH an aquarium chiller and heater. The advantage of these controllers is that they can minimize any large fluctuations in temperature.

There are many types of aquarium chillers on the market. Some of the more popular types are listed below (the features have been listed underneath):
