I have a cubby hole above my fireplace (gas, not woodburning). The
cubby is roughly 36" square and is designed to house a television. My
TV is too big for the cubby, so I had planned on using this area for a
fish tank (we don't use the fireplace). I bought a 40-gallon tank and
it fits perfectly. Now however, I'm worried about the weight. Using
rough calculations, the water in the tank will weigh about 320lbs. The
tank itself probably weighs about 50lbs and I had planned to put about
40 lbs of live rock in this tank. To be safe, I'm estimating that the
cubby hole needs to support ~500lbs. I don't think the cubby was
designed to support that much weight. Our house was built last year and
I've contacted the builder to find out how much this area can hold.
He's not sure exactly, but says that the area should hold a 35" TV
(average 35" TV weighs about 175lbs).
So my question is--how can I reinforce this cubby hole? Is it in the
realm of a weekend-type job? Or would this take major restructuring?
Thanks for any advice!
