We've just bought a new house... and as this is a mostly permanent arrangement my wife has granted permission to start the set up procedures on the 55 gallon. I want to go saltwater with FOWLR maybe moving into reef once the budget allows proper lighting. The question though is this... I'm sitting and thinking about where I want to put this tank and realizing that most of the house stands over a 10 foot tall "Crawl" space. How much weight are we talking about on a 55 gallon with standard live rock and sand and 20 gallon sump, and do y'all think it'll be enough of an issue to get someone out to see if the floor can support the weight? Anyone have a guess who would be best to judge.. a contractor or an architect?
