Hi temp-broken heater
Noticed the thermometer on my 55 last night was reading 81.....odd I thought, dials on two hydor 150w's set @ ~75. Noticed one had the indicator light on, so I turned it down, thinking that it was not properly calibrated. This am the temp in the tank is still high, and the indicator light was still on.
Pulled the heater out of the tank...seemed heavy. Argggg..
Glass was cracked and full of water. I'm sure it was one of the 1/2" guppy fry body slamming themselves against the heater or....
Anyway, that's the first time I've ever had a heater tube break. And apparently it kept asking for heat. Glad there was no electrical shock thing happening, though I did have the common sense to shut off power before playing with it.
Maybe I'll look into other types of heaters next time around, though this could just be a matter of 'Sh** Happens'.
