As the move-in date for my house draws near, I get to thinking of my 90g tank and where I will set it up. I've got a slab foundation, so I can't run piping under the house. However, if the tank backs up onto an exterior wall I was thinking I could put the sump and equipment outdoors. The side of the house by my living romo is kinda a dead space, so I figure I could built a simple well insulated chest where the sump and equipment would live. Actually, I could even just build the sump into the shed in the form of a plywood sump. Hmmmm. Thoughts?
