I've had a Visi-Therm Deluxe Heater (50 watt) in a 12 gallon (MarineLand) tank for all of about 10 months.
Yesterday afternoon, I found that my 1 Otocinclus had died overnight. I scooped the poor fellah out, but had to leave the house for a couple of hours before I could look into the problem.
On my return I lifted the hood and was greated with a big updraft of heat. The thermostat had died on the heater and it was now permanently on. I put my had in the water and, at a guess, I'd say that it must have been around 110F in there! How my Gouramis survived, I'll never know
For now, I've put another, identical heater in there from another tank that really doesn't need it; I'm hoping that my lone Betta fish won't mind this ommision.
Anyhow, I'm looking for some advice on a new 50 watt heater. I was considering an Ebo Jager but have read mixed reviews.
Recommendations and advice will be greatly appreciated
