So I sometimes see racks with uth used with the sweater boxes, but no heat light. Are heat lights not really needed? Do people who use those racks just heat the whole room? And how big are 32 quart sweater boxes anyway? I feel like a 55 gallon tank is as small as I really want to go with a adult bp, but I need some sort of system so I don't have 7 55 gallon tanks in my living room, and no other furniture!
