Review on 🐠 Petzilla 4-Fan Aquarium Chiller Cooling System for Salt and Fresh Water Tanks - Fits Aquariums with Lip Width Less Than 1/2 Inch by Brenda Smith

I put this in the sump of my reef tank. I used a cooler last year and it wiped out my electric bill. I hope that makes it better. I would have liked the four fan version but it wasn't on the list. This keeps my tank at 78.8 and I love it. 4 stars because it would be better if it opened all the way so I could mount it on the edge of the tray, but other than that it gets the job done, it's low voltage so it shouldn't kill my electric bill. EDIT: I just took this down because temperatures in the Northeast are approaching calendar and one of the three fans is dead. I don't know how long he's been dead. Changed to three stars because it should last more than a few months. Maybe even in the return window. I think I might just buy some quiet computer fans and replace all three with them.
