Our 250W submersible 3618090 Aquarium Heater today malfunctioned and overheated bringing the temperature well above 90ºC in my son's 75 Gallon freshwater tank.
The sudden increase in temperature caused us to lose all our fish expect one Gouramis.
The heater was only 3 years old and never modified in any way.
Devastating day in our house.
Anyone else experience a similar situation? Very hesitant to purchase another similar product.
