I am planning on upgrading to a 55 gallon tank and merging my fish from my other tanks. We live in a house over 100 years old and where I want to put the tank is in front of a small fireplace that we don't use. It has a stone hearth, brick actually and is quite level. I am assuming this hearth is probably stone all the way to the ground underneath as in this section of the house it has a crawl space Also, my support beams are running opposite the direction the tank will be sitting. I have never had a tank this big and just wanted to make sure I am not missing anything. Does anyone see any problems with this placement? There is a spinnett piano in this location right now and I am guessing it weighs as much or more than the tank will. Oh, and I plan to attach styrofoam in front of the fireplace opening to eliminate any possible drafts. Thanks for any input?
