Comments: abused this chiller from 12/08 till now. removed the cover stuck it under a 180 stand then hit it with 3 400w halides and 140w of floresents. may have under rated for the task at 1/2 horse power but ran for at least 8 hours a day without a whimper. only reason the abuse stopped is because of an led upgrade in lighting. now it just sits there quietly waiting for more abuse.

Comments: Longevity I can't speak to because I've only had it a few weeks, however, it is definately a quality machine made in america. They supplied Aqualogic's controller with the purchase and that is also a quality part. The compressor is very quiet - like a good refrigerator sounds. The fan moves alot of air and you will notice that sound. It's not horrible but don't put the unit next to your couch and watch tv. The low hieght of this unit (11") allowed me to hide it on top of a kitchen cabinet behind the wall the aquarium in on.

Comments: Been running this chiller for several months on a 120 gallon reef tank w/ 40 gallon sump here in the Northeast. I'm using a MAG 5 pump. So far so good. Cycles on and off normally. Easy enough to install. Without the chiller my tank would run high 80's near 90 in the summer. chiller maintains a 78F using a Ranco single stage controller.

Comments: I bought this used more than six years ago and it still works wonderfully. It was slightly noisy when in operation but not too bad. However this year it was really bad as soon as the high temps of summer hit. Took the cover off and noticed the large fan that draws air through the condenser or radiator was loose and causing the rukus. Tightened down the fan and now I can't even tell when it operates. Amazing product.
