Mine stays between 78-80. I think the highest I've seen it go is 80.1.
And in this lovely place we've had 9 straight days of 110+ degs. Top temp was 116 a couple of days ago
Needless to say I am going through topoffs like a madman...average about 2 gallons of RO every day.
79 on my 55gal tank. Temps fluctuated quite a bit before I got my chiller, but now it's at a rock steady 79 degrees, day or night, hot or cold.
I lost some corals when the temp spiked to 86 one day-thats when I decided to get that chiller!

83 FTW!!! This is about where mine sits during the day in the summer. Drops to about 81 during the night.
