Yep it happens. More often that you might think. The advise I've quoted is actually very good. It also provides some redundancy if one fails to add any heat too. It's especially good if you have a larger tank.

Tetratec heaters are'nt bad.

That's what I plan on doing when I need to replace the heaters in the larger tanks.

thanks for your advice everyone.I unfortunately cleaned my tank out before taking a photo and ive disposed of the heater so thats my fault.
I like the idea of two smaller heaters. Can i just clarify though,that would mean that if i need 300w i can use two 150w heaters set to correct temperature?

Yes that would be the idea!

Would keep your tank the right temp, but act as insurance each way if one broke.

All i've ever done is ran the in tank heater off a habistat on/off thermostat. If the in tank heater fails and sticks on the habistat - set 2 degrees higher - will turn it off. I've had 3 fish tank heaters stick on over the years in my marine tanks - danger of bi-metal thermostats i'm afraid, but the habistat has saved the tank every time.

Cheers.

I am now trying a heat mat on the outside back of the tank between the glass/polystyrene running off a habistat pulse proportional, with the probe in tank.
It's a 2' cube tank, room temp 19c (night) 21c (day) and the heat mat is 17"/11" 20w.
It's holding a perfect 26c water temperature for the last 5 months. And all for 20watts!
