My heater has broken and no longer works. I am wondering what the best brand of heater is to buy and how many watts it would need to be for a 29 gallon tank.
I'd recommend Tronic or Ebo-Jager as reliable brands to consider. Feel free to do a search to answer any questions on these. You'll find a lot of excellent information.
50 watt would be a little to low, 100 watt would be overkill but it would definetly be good for your tank, and that way if u ever got a bigger tank, you could use the 100 watt, and maybe add more. Id go with the 100 watt tronic/juger. Godd luck!
100 watt isnt really overkill... the general rule I see is 5 watts per gallon for tanks under 50 gallons..
150 watt would be ideal
100 watt would work
50 watt wouldnt
Two 50s would be good for a 29, as long as it's not in a room that experiences dramatic temp shifts. (In a room that gets cold at night, for example, a pair of 75s might be better.)
