It was a pretty close call yesterday. I almost boiled my entire tank (figure of speach). I guess before i left to work, i accidently bump my neptune temp probe and the reading somehow dropped to 22*F. So, when i got home. Everything looked normal, lights were still off and fishes were swiming just fine, except for the nemos they were erraticlly fanning their eggs. So, i did my usual things around the house. As i was sitting down and playing with my Iphone. i launched the Neptune Iphone apps and noticed the tank temp was at 22*. That off??? So, I walked over to the tank and found the temp probe was slightly pulled off. When i inserted it back in, the real reading come up and it was at 89* :O I immediately turn my chiller and fans on, but it too 4 hours to drop to down to 78*. I guest, my heater was trying to bring my controller activated the heater trying to bring my temp back up. When the lights turned on, i noticed a few corals did not make it. Some of the corals looked pretty stress but still have some polyp extension. So will have to see how they turn out within 24 hours. Neathless to say, this was a wake up call for me to redo my AC programs. I spent half the night redoing my programs with added disaster prevention into it. I also manage to have my alarm and email notification working. Good lesson to learn and not to procrastinate on improtant stuff like adding an extra prevention, just in case..
