    i come home today and my 55 gallon tank, with two 200w heaters, is at 92 degrees. i did a water change yesterday 50% and i adjusted one of my heaters.

    Well, it sounds like there was an issue with the heater adjustment. 92 is pretty warm, but I assume your fish survived fine?

    I never adjust a heater unless I will be around for the next several hours to make sure that it's where I want it to be.

    Depends on how cold your house gets. What brand is/are the heater/s?

    200w should be enough for a 55G, depending of course on how cold the room (as stated). 3-4W per gallon is my rule of thumb, the house rarely gets below 54*F.

    If you're going to run the two heaters, set one slightly lower than the other. I have one set at 80 and the other at 77 (My reef tank). If the tank happens to cool down too much, the second one kicks in.
