What heater would you recommend


I have a new 30 gallon tank with a heater that came with it when I bought off someone on Craigslist.

Lately I have noticed changes in the water temp through my thermo so I think it's time to replace the heater.

I just don't know which heater would be best for a 30 gallon tank.

If you guys could give me some of your opinions that'd be awesome.

Thank you.

I'd say a 50 watt or maybe a 100watt

I have a aqueon 150 in my 29, it may be overkill but my old apt is very drafty, it fluctuates .5 +/- depending on how cold it is outside, I have a 100 in my 20, same variance. Also keep in mind the ability to crank up the heater to fight ich..
I'm not really here... fell in the tank and my phone is just that smart

Here is a link to the size chart which varies depending on the increase in degrees of the ambient air in your room.

I have a 150 Watt Marineland submersible in my 29 gallon and like it.
