I have two thermometers. One is the coralife digital which is about two inches long. The other is a little bigger and is called the Big Digital Temp Alert by Pentair Aquatics. The problem is that the temperatures are not the same. The probes are located in the same area of the tank but the temps are almost 2 degrees off. The Coralife is higher than the other and I believe it is the one that is not correct (at least that's what I hope since it displays the higher temp). Has anyone had any experience with either of these two thermometers?
