Aquarium Heating and Cooling

Controlling the temperature of your aquarium is vital to the health of your fish and plants. In addition to filtering water, proper nutrition, and pH balance, the water temperature has a direct impact on both the health of your aquarium inhabitants and your enjoymet of it.
Most hobbyists agree that a reef tank should be kept at a temperature between 78 degrees and 83 degrees Fahrenheit (26 to 28 °C). Radical temperature shifts should be avoided as these can be particularly harmful to reef invertebrates. Depending on the location of the tank and the conditions therein (i.e. heat/air conditioning), you may need to install a heater and/or a chiller for the tank.
