83 with ac/fan...tried the two liters of ice and they didn't budge the temp....i'll try it again tomorrow...I went over 90 (92-93 if i had to guess. thermomemter only goes to 90)in that first heat wave we had, and nothing died...
79F and still waiting for some hot weather (no AC yet). If the tank temps are high with this weather, now is the time to figure out how to cool the tank before summer really arrives.
