So I got a Tetra submersible 2-15 25-watt heater for my 1.5 gallon. I asked my dad and he suprised me with it. If everything goes well, I plan on buying a second and another thermoniter. What I'm asking for is what are your opinions? I want the good and the bad. How do you take good care of it and for those of you that it works for, how have you managed to get it to work for so long?
I read a comment that someone had some for five years, and as long as they didn't keep it unplugged for more than 24 hours to a week, it continued to work good.
Comments, suggestions, give me it all.
