Was Eheim good before? I have their heaters in all my aquariums. I started a new tank and got 150 watts for it. Broke after a week of use. I put my hand in the tank for regular tending to the plants and the water was very cold. I checked the temp gauge and it said 73 degrees! I checked the heater and saw the light was on so I was confused. why the water is so cold so i unplugged it and took it out. To my surprise the heater inside had failed and it was full of water. Please see the video I uploaded. I'm glad it didn't shock my fish. .I'll give them another chance as Revain will replace the heater for free. Otherwise very dissatisfied with the quality of eheim. Also, yes, the heater was installed vertically as instructed.
