i might build a shed in my backyard for my ever increasing collection. assuming i fully insulate the shed, and use ample heating for the tanks, would that be good enough to keep my fish warm? i know alot of people that just put their tanks in their garages with no probs, and although the temp outside ranges from 20-90f(western washington) i'd say its usually 40 during winter and 70 during summer average. alot of tanks in a small area that is fully insulated should basically heat itself off the tanks if you get my drift.
