Heaters, Chillers, & Thermometers
Much like our own housing, aquariums need heated and cooled to maintain a comfortable temperature for fish if a great deal of heat is being generated by lighting and filtration. An aquarium chiller can bring temperature down in the tank several degrees when connected and an aquarium heater will help to either warm an aquarium or keep temperature stable. Monitoring the temperature of the aquarium is also very important to make certain the heating and/or cooling equipment is working properly so all aquariums should have a thermometer of some type installed on it.
