    Hey FishLore,

    So I noticed that my tank temp drops to 76 degrees overnight and ends up at ~77 degrees during the day. Should I be concerned about the quality of my heater? It's the AGA one that came in the Aqueon tank kit.

    Naw, there will always be a fluctuation in temperatures since the room temp is a factor. If your tank bottoms out at 76F, you may want to push it up a degree or two, depending on the fish you'll be keeping.

    I set my heaters to a level that maintains a minimum temperature. And, I don't worry about the daytime high temp unless it gets too excessive. As I do not have AC, I have to turn down the heaters and even take steps to cool my smaller tanks.

    I have the stick-on digital thermometers and they vary in their readings according to the room temperature as that also influences the temperature of the glass which is what they are measuring.

    These thermometers are only a guide and temperature is best taken accurately with a good quality thermometer.

    VeeSe, remember that a heater will only prevent the water temperature from going below the temp the heater is set for.

    The heater has no ability to help on the up side. So if you have your heater set for 76 degrees and the room the tank is in gets to be 80 degress, the water temp would eventually rise to 80 degress. But if the room temp dropped to 60 degrees, you heater should prevent the water from going below 76 degrees.

    Hi jdhef. I do realize the heater can't cool the tank and completely regulate the temperature, but it's weird because I've seen my heater turn on when the tank is at like 77.3 degrees, so it's weird that it drops to 76 sometimes.

    Where is the themometer in relationship to the heater? Maybe one part of the tank is cooler than the other? Also maybe it drops to 76 while the heater catches up? Either way I wouldn't worry.

    Temp fluxuations are normal in nature, it only becomes a problem if they are too rapid/extreme.... a degree at night doesn't seem too extreme for my tetras who are pefectly happy. So I've left my heater as it is...

    Good morning,

    I have moved your thread to the Aquarium Water/Temperature section of the forum.

    Thanks!
