Ugh, cold ass florida, its already killed a couple of my fish (my 2 pbass and a mayan cichlid), my heaters werent strong enough, its been getting in the 30s at night here, its supposed to start getting warmer this week though
I run my tanks w/o any heaters, but we keep the house around 72-74 degrees . . . with the lights and filters my tanks are staying around 74-76 . . . so far so good
