Review on 🐠 Cobalt Aquatics Accu Therm: The Ultimate Submersible Heater for Perfect Aquarium Temperature by Sharon Griffin

I bought this heater in March and within ONE WEEK I heard a HUGE explosion! The heater literally exploded like a bomb! It smelled like fire and luckily I was home, otherwise the house would almost certainly have burned down! I contacted Cobablt (manufacturer) and they told me it was "consumer error" because I had a water/air interface when using the heater. The heater was FULLY SUBMERGED the whole time, there was no FAULT on my part! I have two more of the same heaters and they are all SO used! I filed a report with the Consumer Product Safety Commission, it was published, and then the manufacturer filed a comment saying I misused the device and CAUSED it to fail! NO, that did NOT happen. Suffice it to say that the report was subsequently removed from the CPSC website! I will never use any of these heaters again! Fortunately, when the heater exploded, there were no jellyfish in the aquarium. Buyer Warning!
