What is the best Heater for a 29 gallon fresh water fish Aquarium?

A general rule of thumb for heaters is 5 watts per gallon. So for a 29 gallon tank, you'll need at least a 145 watt heater. Round up to 150, and you have lots of heater options. One that I'd recommend is the Visi-Therm Stealth Heater: http://www.drsfostersmith.com/product/prod_display...

If you want to save money and get a lower wattage, you can. Although it will take a longer time to heat the aquarium and will heat a few degrees less than what you set it to.

E-mail me for any questions!

Tetra makes pretty nice, price range friendly submergible heaters...

I have on on both of my tanks.

for a 29 gallon you would probably want a 100 or 150 watt.

something with a top knob that you can adjust the tempertaure level on so that the heater can fluctuate it's automatic on/off plates to keep that desired tempertaure.

and they are pretty affordable...

for a 100 watt, you are looking at 20 dollars maybe?

good luck....

just check the back of the heaters for wattage/gallon ratio...

it will give you the proper wattage to use.

peace, good luck :)

any one thats about 150 watts with a thermostat and a thing where you can change temp easy alot of the time they say how many gallons its good for id also suggest a submersible one:)
