Yes the Marineland Stealth was recalled about 2 years ago for that exact reason... I've heard stories where the heater actually exploded and broke tanks. Others where whole communities were destroyed. Regardless, if you contact Marineland you may be able to file a claim and get a free heater at least. I'm not sure now it may be too late... I sent back half a dozen still working heaters and they replaced them for free... Good luck
