During feeding time I notice the tank was colder. I checked the temperature and it was hanging around 74.4. It was a little old to see that the coral frags I have were not as colorful and recessed. The Toadstool and GSP, that have great polyp extension, where retracted in their body. I had my two month old heater stop working. I took a gamble on only running one heater at the start of the tank. I was planning to add another heater sometime in the future. Those sometime in the future plans can bite you in the *** or never materialize. I threw in my heater from my water mixing station and went to Pet Co. I bought two 200 watt heaters and placed them in the sump. The tank got down to 74.2 on one thermometer and 73.8 on another. After about an hour the tank was climbing back up to 75.4.
I think that they should make a better heater that we can rely on with todays technology. I see and hear too many stories of heater failures. This is a good lesson for me on redundant life support. Someday a controller will be in works.
