So yesterday was water change day, and I forgot to turn the heater back on. So got home from work, about 2:30cst wondering why all my zoas look like crap. Start to go through everything and notice my temperature gauge which is part of the heater was not on. Turned it on and it's reading a toasty 65.6 F. So not heat for 28 hours or so. But before I notice that I removed all the ceramic skulls and tombstones I put in the tank thinking they might be leaching something......

but how could you not noticing having your hand in there when you remove those deco
Sorry about that but it might be time to invest in some wifi thermometers to alarm on low temp. Last time I detected a heater failure by hand and freaked me out
