im at 80 not too happy:anger2:
80 is nothing to be concerned about, assuming you keep your tank at 78.
I came across some information on average tropical reef temps when I was researching Chillers. If I remember correctly..... Worldwide average temp for tropical reefs was 82 degrees, with average high temps reaching 88 and average low temps hovering around 76.
Red Sea reefs had average temps of 84 degrees with high temps reaching close to 90 degrees in some areas.
The article I was reading recommended keeping your tank at 82 degrees, as being closer to natural averages. .
IME, I used to let my 65 gallon rise to about 83 degrees during the summer. I had a target temp of 80 during the summer. I didn't choose this temp, it is just kind of where my "cooling power" maxed out. I had no problems, and was keeping SPS.
Many people slowly raise their target temp from 78 in the winter to 82 during the summer. This is based off the theory that what is more important than your high temp, is the overall swing in temp. If you keep your tank temp at 78 and it jumps to 84, that is a lot worse than if your tank jumped from 82 to 84. In the first instance you will probably have problems, where in the second scenario you might never notice the temp increase.
