Has anyone had any experience with this?

The temperature in my 20 gallon tank is climbing to 85+ during the day. There is no canopy or lighting of any kind on it. It is located in the bay window in my kitchen, but it does not receive any direct sunlight. Oh, the heater has been unplugged, too. I am running an Aqua C Remora w/ the MaxiJet 1200, plus 3 MaxiJet 900's. I have unplugged one of the powerheads, but so far I have not noticed a difference in the temps.

$150 seems reasonable to spend for a chiller for my nano... I just wonder if it's any good!

Any thoughts are welcome!
