Heater - Should I Have Two? If So, Wattage?

    I'm kinda new and setting up a 28 gallon freshwater tropical tank. I've read that some people suggest using two lower watt heaters so that you A) have a back up if one stops heating and B ) so that if one fails and gets stuck on heating mode, it will have a hard time overheating the tank by itself.

    Has anyone done this? Results?

    If you recommend this dual heater setup, what size/wattage heaters would make sense for a 28 gallon?

    For my tanks I just have one heater. If your heater malfunctions your fish just might get fried so there is no point in buying two.

    An 100 watt Aqueon submersible heater would be good for your tank.

    For an Aquarium your size, I use Eheim Jager, its 100w and my aquarium is 36g. I feel you should just get something between 100-200w and/or is suited for aquariums 20-40 US Gallons

    Hmm, so no one in favor of two heaters? I'm just paranoid about boiled fish... :-/

    With two heaters you're not worried about "boiling" fish, you're keeping a spare in case on of them stops heating properly. I always have two.

    If your heater malfunctions in that it remains on and overrides the thermostat, there's not a whole lot you can do.

    Oh... I guess that makes sense. I had read somewhere that if you had a lower wattage heater then it would be harder for it to overheat the volume of water, but I suppose that would only be the case if the ambient temp was leeching heat... or maybe not at all.
