A little backgroud is in order here...
I keep a BUCNH of reptiles. I have a huge "reptile room" that also housing my 125g tank as well. Well due to the requirements of my reptiles the room temp stays in the area of 78-81 degrees. So the tank water stays in that renge. The night time temp MAY dip down to the mid 70's MAYBE. SOMETIMES. And that is during the winter months.
Summer is here in Ga (I HATE Ga weather) The outside temp is is already in the low 90's and the room temp never really gets blow 80 now and, like last season, may get as high as a constant 85. Therefore i am to assume that my water temp will be in the mid 80's
I have posed this question before on another forum, and was told not to worry about getting a chiller, but as summer lays her humid nasty hot blanket over Ga i am getting more worried that the tank temp will be too high.
So...to chill or not to chill?
