Suggestions for heater 2.5 gallon please

[gill2]

If someone could please give a Brand name and model that works well I would really appreciate it.

I bought one last week, First one was a Marina Submersible Mini Aquarium Heater got it home and it didn't work. I than returned that one and bought another and the temp in water is going up and down like a yo-yo.

I know I should get and adjustable now that I read some of the posting but which one works?

Again I have a 2.5 gallon tank. Thank you

I have Elite 25w's in my 2.5g's. Work great.

Thank you so much for your quick response. I'll search on the net on where to buy one.

I bought mine on amazon for like 12 dollars. May have gone up by now.
