I'm no novice to freshwater fish, I've had them for a while and have been somewhat successful. My friend is getting rid of his 90G satlwater tank with lights, skimmers, sumps, pumps, heaters, fans, and hood. Literally throwing in 'the works.' The problem is my house is small and I don't have any room and I'm sure the weight would crush my floor. I would need to put in some sort of support in the crawlspace. I DO however have a detached unheated garage with poured concrete floor. My garage is not insulated and not heated. I live in Southern New Jersey and although it's been a mild winter it's still cold outside. My question is, if i get this tank, can it be set up successfully in my garage? Will waterheaters keep it the right temperature is that a lost cause? Will insulating some of the garage help? Does the whole thing need to be insulated? Is there a small heater that could be added to the room that is safe? I don't want to leave a heater unattended that could cause a fire. I don't want to pass this tank up, and the price is right, but I need someone with experience in the un-heated uninsulated garage department to shed some light on this.
