Is that a Marineland Stealth heater? I thought there was a recall on them.

Sorry to hear about your heater trouble.

I was using a 250W Marineland Visi-Therm in my 72. One night I kept hearing a buzzing sound. My tank is in my bedroom and my wife heard it too. As I was laying there, I could see the heater LED come on and the buzzing sound would start, then a few seconds later it would go off and the buzzing would stop. Turned on my lamp and when the heater would come on, the buzzing would start, and all the fish would freak! I unplugged the heater (glad I did) and removed it from the tank... The glass was FULL of water, I was shocking my fish. Glad I didn't reach in the tank, or it would have shocked me!

The only spare heater that I had was a 100W Aqueon Pro, so I put it in there thinking I would add a second 100W down the road. I liked the idea of having two smaller heaters to not cook my fish if one died.

Well, months later, I'm still only running the single 100W and it's working great! Granted it does take a long time to raise the temperature, but it will keep the water steady. I also get the piece of mind that if it were to stick on, I would notice it way before it got to hot for the fish.

I'm now a firm believer that you can use a smaller heater than the suggested heater size from the MFGs.

Just something to chew on?

Thanks Brian,

I am using a smaller heater since I keep my ambient temp in the house at 76 anyway

Just a follow up, Tetra offered to send me a new heater - I turned them down, telling them that I am uncomfortable utilizing their heating products any further.

I also asked them instead to put a safety system in their heaters in the future to prevent them from failing "on".

When I bought a used tank off Craigslist I naturally got all the equipment, one being a 300w tetra heater. It looked pretty old but I tested it. Damn thing heated my 75 from 69 to 85 in 30 minutes and I had it on the lowest possible setting! It went to the garbage.

I use two 250w in my 125s to prevent stuff like this, one alone on all the time takes days to heat the tank. I've tested it. I had two of the recalled stealths, oddly enough one stopped coming on one week, the next the other wouldn't go off. tank temps barely moved. I got 47$ each as a check from the recall and bought eheim Jagers. they are great.
