Ratings & Reviews
So far so good
I have two of these in my 150 gallon. They do heat up the water but the temp gauge is off. I have it set on 71 to keep my tank at 77. When I had it at 77, my water temp was in the 80's. so it works, you just have to play with it a little to make sure the temp is where you want it.
