Help your fish chill out on hot summer days or under those intense reef lights. This water chiller uses a titanium heat exchanger to resist corrosion while your water is cooled within a range of 50 to 85 degrees Fahrenheit. The slim design and sleek black case eliminate the eye sore of chillers gone by, and a cool ice blue LED light lets you know your chiller is working. Programming is even made easy with a simple keypad to display an accurate temperature. A hot product and a cool choice for any aquarist. Size: Unit is 16.5" x 8.25" x 21".
