📖 Overview
Chillers use the same technology as a refrigerator. Water is pumped through a heat-exchange coil where refrigerant absorbs thermal energy and releases it outside. Reef tanks with high-wattage lighting often generate excess heat that a chiller keeps at bay. Coldwater species (some plecos, hillstream loaches, rare cichlids) may require chillers in warm regions.
