Piranhapat, glad that you did since I have no idea about these recalls until this happened.
I really feel that it is VERY unusual for this to happen to heaters and that's why they are doing a full recall and stopped production...I've been in the aquarium hobby for over 20 years and when heaters failed in my cases, they normally don't turn on. And when they do stay on, they don't heat the water to 115F.
I have to thank God that it didn't happened any earlier and it was right on the 10th day when i came back from TDY....My mother, who was caring for them when I was away, would have had a heart attack!
On a side note, the survivors of over 115F were:
1) Duncans
2) Elegance - to my greatest surprise! I always thought these were a pita to keep but she's been with me for over 2 years! I got it from Ryan (a vendor) along with the acans.
3) xenias
4) mushrooms
5) 2 small colonies of Acan Ech
All wiped out were the Australian Acans, blasto, acro(s) ....
