What temperature does everyone keep there tank at?
 

Also how much can the temperature in the tank fluctuate before I should be worried? Mine seems to vary during the day

I aim for 78°, it dips as low at 77.5 overnight and as high as 79 during the day when all the lights are on. I think anything less than a 4° swing is ok.

between 79.5 and 81

I keep my temp at 78.0 F. My lights 3 x 250W will move the temp to approx 79.5. In the summer I use a chiller to keep the temp within a max of 80.5F

I go anywhere between 78-83, or at least I did in my old place.

Thermometer reads about 78-80F all day.

80 at night and up to 84 during the day

78

79-83

78 - 84ish

78 and in the summer up to 82 before i turn the ac on

79 to 80, and in summer it may get up to 84-85 on some days.

78 to 79F

One time I had a faulty glass thermometer that showed my temperature as -6F of what the REAL temp was. ie; it would display 80, but water was really 86F

Advice for everyone to check and see if your thermometer is actually accurate :mrgreen:

I hear ya, great advice, I've had the same thing happen, now I have 3 thermometers (2 in the tank- 1 digital, 1 old school- and 1 in the sump) to make sure the temp is accurate.

77-78

78-80

I aim for 60 but it sometimes climbs to 61 or 62.

Mine is at 76-77

76-78 is what mine stays at. once i unplugged my heater and my tank went down to 69 before i realized it over 2 days. brought it back up to 77 and all was good.

79.5 It almost never fluctuates.

Got down to 74 the other day with the wind storm and power outages. Normally 79 to 82.

79-82

80-81

78 to 79

79- 82

78-84

What's this all about????

We didn't go metric until after I graduated, 26-27º is below freezing :razz:
