absolutelyAll of the heaters on Amazon have people complaining the Heater killed their fish, I guess some could be true but I believe most of it is operator error.
I don’t bother with amazon reviews. Come straight to fishloreOn Amazon, I keep seeing reviews of heaters overheating and killing fish
I have a question. By bookshelf tank do you mean a longer tank? I'm buying an 11 gal "bookshelf tank" by Lifegaurd Aquatics and I'm wondering if the 50W heater I have won't be enough.Take a look at the Neotherm heaters, or now Cobalt Aquatics.
I have a 75W in my 12gl QT tank (bookshelf tank losing heat fast, keeping temp steady in unheated room), as well as a 100W in my 20gl.
They are non glass, temp is easy to set and check.
