I never said to use a single heater. If the 3 300w heaters are not up to the task then, another heater is the way to go. I keep multiple heaters in my tanks where extra heat is needed. Otherwise, the building is heated for my tanks.
Anyway, judging by the tone of your responses and the abysmal stock selection for that size tank, I'm done with this thread. I hope your fish don't suffer further.
