This might be really obvious and I'm just missing something but I have a question pertaining to tank temperature. So I normally keep my tank between 77-78 degrees but during the winter I like to turn my fan on and open the windows. I haven't been able to do that this summer because my tank drops all the way down to about 75 degrees. Now while the winter was variable I'm curious about the summer and what fluctuations may occur with the air conditioning or heat from outside. Just curious as to what you guys experience and how you cope with it. Oh yeah, my tank is about 4ft away from my bed, which was a huge mistake lol
