What heater would you recommend

[D_Tristan22]

Hello

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..

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.
