Three Types of Aquarium Water Chillers
A discussion of the importance of having both a aquarium chiller and a heater. A comparison between inline, thermoelectric, and dropin chillers.
Many small aquarium systems will only have a small heater, but if you have a large aquatic setup and very expensive fish, you also need a device to cool the water if the setup overheats. Depending on the breed, many types of fish are extremely vulnerable to temperature fluctuations.
What types of water chillers are available?
Inline aquarium chillers are used in systems that are over 55 gallons, and are most common in saltwater setups. They are available in the sizes up to one horsepower power, and they may require plumbing.
Another common type of aquarium chiller is the thermoelectric chiller, which are mainly used for smaller tank systems which are under 55 gallons. Usually, in a larger system that has fast water flow, this type of thermoelectric chiller will be insufficient to cool your tank. A thermal electric aquarium chiller uses a fan in order to dissipate heat, and requires adequate ventilation.
Drop in chillers are the last type of aquarium cooling device that you may want to utilize in your aquarium setup. This type usually uses a probe that is placed into a sump filter, and is frequently used in saltwater aquariums. Dropping cooling systems do not usually require any plumbing, and they work excellent in smaller tanks for fish that have a high sensitivity to temperature.
Remember that whatever type of water chiller you use in your aquarium, it is usually necessary to provide adequate ventilation for the fan exhaust, and if you are concerned about price, drop in chillers are usually the most affordable.It is important to remember that you should not underestimate the susceptibility of tropical fish to temperature fluctuations, and most professionals and hobbyists who own saltwater tanks realize the importance of using an aquarium chiller in conjunction with a heater in order to maintain constant temperatures that are conducive to healthy aquatic life, especially considering the investment that one can make in an artificial saltwater reef.
