Keeps the tank below 28, was hitting 31 before this fan. It's also a lot quieter than my old one.

This thing works great, makes very little noise and it is able to cool, my 200 l tank a few degrees in only a couple of hours.

Very happy with it, again, you can't go wrong with this fan.

Funcona perfectamente,lo recomiendo
